Definitions for "Electromagnetism"
Magnetism arising from electric charge in motion.
Magnetism that is created by current flowing through a conductor.
Magnetism produced by an electric current; electromagnetism was discovered when it was observed that a copper wire carrying an electric current can magnetize pieces of iron or steel near it. It was concluded that electrical and magnetic forces are intimately related, since a changing electric field produces a magnetic field, and vice versa.
