Does Magnetic Encyclopedia

Magnetism Encyclopedia Britannica Britannica

Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. Learn more about magnetism in this article.

Magnet physics Encyclopedia Britannica

Magnet, any material capable of attracting iron and producing a magnetic field outside itself. By the end of the 19th century all the known elements and many compounds had been tested for magnetism, and all were found to have some magnetic property. The most common was the property of diamagnetism,

Magnetism Wikipedia

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.The most familiar effects occur in ferromagnetic materials, which are strongly

Magnetic flux physics Encyclopedia Britannica

17-08-2020· Other articles where Magnetic flux is discussed: electromagnetism: Faraday’s law of induction: found that (1) a changing magnetic field in a circuit induces an electromotive force in the circuit; and (2) the magnitude of the electromotive force equals the rate at which the flux of the magnetic field through the circuit changes.

Magnetic Levitation Encyclopedia

magnetic levitation or maglev (măg´lĕv), support and propulsion of objects or vehicles by the use of magnets. The magnets provide support without contact or friction, allowing for fast, quiet operation. In a typical system, the vehicle, which resembles a railroad car, travels above a guideway.

21-01-2011· These magnetic records also show that the geomagnetic poles have reversed—changed into the opposite kind of pole—hundreds of times since the Earth formed. Earth’s magnetic field does not move quickly or reverse often. Therefore, it can be a useful tool for helping people find their way around.

Magnetism Article about magnetism by The Free Dictionary

The transfer of magnetic interaction, which forms a bond between spatially separated bodies, is accomplished by a special material carrier, the magnetic field. It, together with the electric field, is a manifestation of the electromagnetic form of the motion of matter. Full symmetry between the magnetic and electric fields does not exist.

Magnet and Magnetism Kids Britannica Kids

A magnet is a rock or a piece of metal that can pull certain types of metal toward itself. The force of magnets, called magnetism, is a basic force of nature, like electricity and gravity. Magnetism works over a distance. This means that a magnet does not have to be touching an object to pull it.

Where does magnetism come from? Gravity and Levity

19-04-2015· The only materials that a magnet will stick to are ones that already want to be magnetic themselves, like the iron on the door of your fridge. Putting a magnet on your fridge magnetizes the iron in the fridge door (or, rather, it organizes the already magnetic domains in the iron), and then the door can pull back on the fridge magnet in the usual north-to-south way.

How Magnets Work HowStuffWorks

Magnetic domains that are oriented in opposite directions cancel one another out, so the material does not produce a net magnetic field. "Magnet." Encyclopedia Britannica Online. 3/2007 (3/9/2007) Epstein, Arthur J. and Joel S. Miller. "Magnet." [email protected]

Magnet Simple English Wikipedia, the free encyclopedia

A magnet is a very special metal.When a magnet goes near a special kind of metal or other magnets, and the poles (sides) touching are opposite, it will pull, or attract the other metal or magnet closer. Also, if the two poles are the same, the two magnets will push away, or repel, from each other.This is called magnetism.Magnets can make some other metals into magnets when they are rubbed
