Magnetic Materials Background: 2. Origins of Magnetism
... Almost everyone is familiar with what a magnetic material can do but very few know how a magnet works. To understand this phenomenon one must first grasp the inextricable connection that exists between magnetism and electricity. A simple electromagnet can be produced by wrapping copper wire into the ...
