... Ferromagnetic materials include iron, steel, nickel, cobalt, and certain alloys. They become strongly magnetized in the same direction as the magnetizing field, with high values of permeability. Paramagnetic materials include aluminum, platinum, manganese, and chromium. They become weakly magnet ...

... axis. Find the bound charges. Now sketch the electric fields (i) for L a, (ii) for L a, and (iii) for L ≈ a. b) A very long cylinder, of radius a, carries a uniform polarization P~ perpendicular to its axis, not radial direction. Find the electric field inside and outside the cylinder (using one ...

Magnetism
... Magnets in your everyday life have the same properties as magnetic rocks because they are made to have them. Any magnet, no matter what its shape, has two ends, each one called a magnetic pole. The magnetic effect of a magnet is strongest at the poles. A magnet always has a pair of poles, a north po ...

... Faraday’s Law, and the induced emf and induced current associated with it, is one of the most practical ideas in physics — it lies at the heart of most devices that generate electricity. The basic components that make up an electric generator are quite simple. All we need is a conducting loop expose ...
