Introduction to Electricity & Magnetism
cpb-us-e1.wpmucdn.comMagnetism • Natural magnets have North and South Poles. • Like poles repel and opposite poles attract. • Magnetic field lines flow from North to South. • Natural magnets are made from Iron, Nickel, and Cobalt. • Magnetic substances can be induced by magnets to become magnets.
Electricity and Magnetism - City University of New York
www.kbcc.cuny.eduMagnets are materials that produce a magnetic field of their own. Extreme examples of magnets are (1) "hard" or "permanent" magnets (like refrigerator magnets), which remember how they have been magnetized, and (2) "soft" or "impermanent" magnets (like the material of the refrigerator door), which lose their memory of previous magnetizations.

(iv) We cannot isolate the north, or south pole of a magnet. If a bar magnet is broken into two halves, we get two similar bar magnets with somewhat weaker properties.
