		Earth's Magnetosphere ^Votes:0 The Earth's Magnetic Field Click on image for full size version ( 71K GIF ) Windows Original Image The Earth has a magnetic field with north and south poles . The Earth's magnetic field reaches 36,000 miles into space. The magnetic field of the Earth is surrounded in a region called the magnetosphere. The magnetosphere prevents most of the particles from the sun, carried in solar wind , from hitting the Earth. Some particles from the solar wind can enters the magnetosphere . The particles that enter from the magnetotail travel toward the Earth and create the auroral oval light shows . The Sun and other planets have magnetospheres , but the Earth has the strongest one of all the rocky planets. The Earth's north and south magnetic poles reverse at irregular intervals of hundreds of thousands Read More Go to Site

		History of Electricity and Magnetism \|Multimedia Engineering ^Votes:0 Multimedia Engineering The History of Electricity and Magnetism Web mediaeng.com Way Back When Arks were Arks and Arcs were Arcs and Sparks did Fly The earliest philosophers recorded in their writings little information on the existence of magnetism and electricity. It is apparent, now, that even from the beginning of civilization there were several manifestations of electrical existence recognized by man. Regardless of one's belief of how existence began, it would be difficult to imagine that turbulent period without the presence of lightning . Undoubtedly, lightning has been around since before meteorologists. The early Tuscans, perhaps as early as the 8th century B.C.E., believed there were as many as nine Gods who possessed the ability to deliver lightning bolts.

Ferromagnetism Example: Problem 33.22 33.4. Diamagnetism 33. MAGNETIC MATERIALS 33.1. Magnetic Moments An electron moving in an orbit around a nucleus produces an average currentalong its orbit. As a consequence we can associate a magnetic moment with theorbiting electron. Suppose the electron is moving with a velocity v in anorbit with radius r. The period of this motion is equal to (33.1) During one period T the charge e will pass each given point on the orbit. Thecurrent associated with this orbit is therefore equal to (33.2) The magnetic moment associated with this current is equal to (33.3) It is common to specify the orbit of an electron in Read More Go to Site

		Magnetism ^Votes:0 Next: The Magnetic Field Up: Main physics index Previous: Magnetism Magnetism The movement of a compass needle towards the North Pole and the attraction of a fridge magnet to the refrigerator are two examples of magnetism in our everyday lives. In this chapter we will examine a magnetic field in detail and begin to explore the sources of magnetism. We will also begin to see a connection between magnetism and electricity which, when developed further, is at the heart of one of the most successful theories in physics.

		Magnetism ^Votes:0 Site Map Magnetism Magnetism &nbspThe ancient Greeks, originally those near the city of Magnesia, and also the early Chinese knew about strange and rare stones (possibly chunks of iron ore struck bylightning) with the power to attract iron. A steel needle stroked with such a "lodestone" became "magnetic" aswell, and around 1000 the Chinese found that such a needle, when freelysuspended, pointed north-south. &nbsp The magnetic compass soon spread to Europe. Columbus used it when he crossedthe Atlantic ocean, noting not only that the needle deviated slightly from exactnorth (as indicated by the stars) but also that the deviation changed during thevoyage. Around 1600 William Gilbert, physician to Queen Elizabeth I of England,proposed an explanation: the Earth itself was a giant magnet Read More Go to Site

		Magnetism, what is it, and how it works. ^Votes:0 The earth's magnetic field does not run parallel to the earth's surface. The angle of magnetic dip is the measure from the horizontal plane to the magnetic lines of force. This also varies depending on one's position on the surface of the earth. MAGNET FACTS Magnetism - although scientists and researchers have been able to harness the power of magnets for the semiconductor and microprocessing industries, they have yet to determine what a magnetic field is..... Some current hypothesis include the following. Similarities which scientists observed between electricity and magnetism led them to suggest that magnetic properties are possibly the result of forces between electric charges in motion. Substances which can be induced to become magnetized in a magnetic field are called ferromagnetic. S Read More Go to Site

		Relativistic Electrostatics => Magnetism ^Votes:0 Magnets Held Up by Length Contraction? T he effects of magnetism follow from the fact that moving charges see current-carrying wires as charged, due to relativistic length contraction which upsets the wire's apparent charge balance. Hence from special relativity and the fact that opposite charges attract, one can show that like currents in neutral wires attract . This is illustrated with a couple of x-ct plots below. The effect has practical applications because the electrostatic force is noticeable with only very slight (in this case apparent) charge imbalances. To see if relativity is at work, one thus might have to look no further than your refrigerator door! For some related links: Dan Shroeder's talk on this subject and our derivation .
