Magnetic Materials Background: 2. Origins of Magnetism
... 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 ...

... When a wire carrying a current is placed in a magnetic field, a force acts on it. The direction of this force depends on the direction of the current and on the direction of the magnetic field. If either is reversed, the direction of the force is reversed. When the field and the current are at right ...
