This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the 6th, 7th' and 8th April 1983, a conference entitled "Magnetism, planetary rotation and convection in the Solar System" was held in the School of Physics at the University of Newcastle upon Tyne. The purpose of the meeting was to celebrate the 60th birthday of Prof. Stanley Keith Runcorn and his, and his students' and associates', several decades of scientific achievement. The social programme, which consisted of excursions in Northumberland and Durham with visits to ancient castles and churches, to Hexham Abbey and Durham Cathedral, and dinners in Newcastle and Durham, was greatly enjoyed by those attending the meeting and by their guests. The success ofthe scientific programme can be judged by this special edition of Geophysical Surveys which is derived mainly from the papers given at the meeting. The story starts in the late 1940s when the question of the origin of the magnetic field of the Earth and such other heavenly bodies as had at that time been discovered as having a magnetic field, was exercising the minds of several scientists; notably P. M. S. Blackett at Manchester, W. M. Elsasser at the University of Pennsylvania and E. C. Bullard at Cambridge. Two alternative mechanisms were proposed. In one the magnetic field was in some way connected with the distributed angular momentum of a rotating body; in the other, electric currents in conducting parts within the body were proposed as the source of magnetic field.

This book was released on 2019-03-09 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurry up and get YOUR copy NOW❗ Discovering Secrets about EARTH MAGNETISM: Problems With Electric Charges, On Earth, In Atmosphere, In Van Allen Belt And On The Moon❗ Dear Readers, I study and compile my research results in a book. My purpose is to offer my book for publishing in Singapore and distributing to the world. The book is sorted as Earth Basic Science; semi-empirical research, its title is "Problems With Electric Charges, On Earth, In Atmosphere, In Van Allen Belt And On The Moon." Since 70th years in Marine University, I did battle with the issue of Earth Magnetism, but tens of questions are left behind when I left that school. Such long time of more than 30-year period seems not enough for me to consider the problems of Earth Magnetism, but I do come back with Earth Science and study Earth Magnetism again. Should we begin with "the spinning & magnetism"? This question has been asked for long ago but known to the world since 1915 when Samual J.Barnet (an American scientist) introduced his invent: the Barnet effect. The effect is stated in general: any neutral object (no electric charge on it) spins to induce magnetism. That scientist, the author of his invent applied such theory to explain the origin of Earth Magnetism. He failed or is not accepted. We now begin again with Earth rotation and its magnetism; nonetheless we don't introduce a shock in science, but we do introduce a new view to Earth Magnetism: it spins with electric charges on it cum in the electric field of some others, that's how it is magnetized. Certainly we are at a large gap away from Samual J. Barnet. The gap is not just 102-year interim; it is a view to magnetism in general and Earth Magnetism in my research. The gap is presented in this book with several chapters in 200 pages. I am neither going to deny the settled theories about E.M nor to make the Geomagnetism up-side-down, but consider the E.M as one constituted by 2 major parts: - The "part I" for sea & land: This mainly comprises 2 compositions that induced by the charges at sea surface and land surface, they are both on Earth. The very special paradox is that "land charges versus sea surface charge in contributing to the E.M whilst they both are moving together with Earth's rotation." - The other-external inducers: is one that contributed by external magnetic inducers such as Van Allen belt, Moon and atmosphere. The simple principle governing this part is that the Earth is rotating in electric fields of many charges; that's how the Earth is magnetized. Meantime, in this part I point out that the Moon is charged and its charge induces magnetism to the Earth during orbiting around our planet in a cycle of 29.5 x 24 hrs. Like any other authors, I wish my book to be printed and sold. Unlike some other author, my book is my claim about my discovery.

Download or read book New Approaches In Geomagnetism And The Earth s Rotation written by S Flodmark and published by World Scientific. This book was released on 1991-01-30 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rotation of the Earth and its relation to geomagnetism are topics that have been under debate for more than a century. In this volume both of these phenomena are discussed in the light of new approaches. Keith Runcorn presents a survey of the papers and concluding remarks. F Richard Stephenson gives a thorough review of the history of the Earth's rotation whilst Stig Flodmark finds an explanation for the Chandler wobbles and the drift of the polar axis. A New Approach to Polar Motion by Losito et al. gives another view of the same theory. The fascinating idea of a single-crystal inner core is discussed by Flodmark and Weber and magnetic rigidity in the Earth is a new concept dealt with by Mörner. The mechanisms behind magnetic reversals, ice ages and earthquakes are other subjects under debate. It is hoped that the present volume will encourage forthcoming debates on these subjects.
Download or read book The Magnetic Field of the Earth written by Ronald T. Merrill and published by Academic Press. This book was released on 1998 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topics involved in studies of the Earth's magnetic field and its secular variation range from the intricate observations of geomagnetism, to worldwide studies of archeomagnetism and paleomagnetism, through to the complex mathematics of dynamo theory. Traditionally these different aspects of geomagnetism have in the main been studied and presented in isolation from each other. This text draws together these lines of inquiry into an integrated framework to highlight the interrelationships and thus to provide a more comprehensive understanding of the geomagnetic field.
Download or read book The Spinning Magnet written by Alanna Mitchell and published by Penguin. This book was released on 2018-01-30 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.

Download or read book CHARGE written by Frank Close and published by Oxford University Press. This book was released on 2024-05-23 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frank Close delves into fundamental particles and forces to find clues to a deep unsolved mystery of physics: why is matter neutral? Human beings have long been aware of the electric and magnetic forces around us, from the electrostatic charge built up by rubbing amber with fur, to the pull of the lodestone, and scientific investigation showed that the two are intimately connected, as electromagnetism. Lightning shows how devastating electricity can be in nature, while humans learned to exploit the flow of negatively charged electrons that make up an electric current. In the early part of the 20th century, the experiments of Ernest Rutherford showed that at the heart of atoms lies a positively charged nucleus. The positive charge comes from protons. Atoms are neutral because the charges of the electron and proton cancel out. And that enables the much weaker force of gravity - always attractive - to dominate at large scales, building planets, stars, and galaxies. Things would have been very different, had the charges not cancelled. As far as we know, the charges of the proton and electron are opposite and exactly equal, even though the proton is far bigger, and composed of three quarks tightly bound within it, while the electron is a fundamental particle. But why are they equal? This is one of the deepest unresolved puzzles of fundamental physics, and forms the driving force of this book. To explore the clues we have, Frank Close takes us on a journey into the quantum subatomic world of particles. He describes the strong and weak forces that operate alongside electromagnetism at these short ranges, and the colour and flavour charges that drive them, as well as the parallels between them, giving tantalizing hints of a deeper unity of all forces that is the dream of grand unification theories. Seeking an answer to why matter is neutral brings us to fundamental forces and particles, the Standard Model, the recently discovered Higgs boson, and the implications of grand unification for the stability of matter. Within this compact volume, Close packs in an extraordinarily rich account of our current understanding and the efforts of the latest ambitious experiments to probe further, and test theoretical possibilities such as the decay of protons.

Download or read book As The World Turns The History Of Proving The Earth Rotates written by Peter Kosso and published by World Scientific. This book was released on 2020-03-05 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'This book offers an excellent explanation of the scientific method and its use, through case studies from astronomy, physics, and philosophy. Summing Up: Recommended. Lower- and upper-division undergraduates. General readers.'CHOICE'In summary this is a lovely, elegant book which reminds us that physics is not an exercise in mathematics but a self-consistent system of thought based on measurement and informed observation which depends on interpretation by the human mind in the context of the science of the day. It is a valuable reminder of the underlying human quality in physics that gets lost in the 'shut up and calculate' methodology of the more esoteric branches of the science.'The ObservatoryWe know the Earth rotates, but how do we know? When and how did it become reasonable to believe that the Earth rotates?This book offers a historical account, from ancient Greek science to the theory of relativity and ultimately to videos taken from outer space, of how this widely known truth came to be. Using an accessible and entertaining narrative suitable for anyone interested in astronomy, physics, or the history of either, Kosso clarifies the use of evidence to prove that the Earth rotates, and deals with the tension between the claims that the Earth is absolutely in motion, yet all motion is relative. The book also explores the general nature of scientific evidence and method, and confronts challenges to science from outside the discipline.
