A group of atoms in a magnetic material in which the magnetic poles of the atoms are aligned in the same direction

Region on a magnet where the magnetic force exerted by a magnet is strongest; like poles repel and opposite poles-attract

The properties and interaction of magnets

Temporary magnet created when there is a current in a wire coil

Electromagnetism is the interaction between electric charges and magnets

A cylindrical coil of wire used to produces a magnetic field when an electrical current passes through the wire

Device that uses electromagnetic induction to convert mechanical energy to electrical energy

Device that uses electromagnetic induction to increase or decrease the voltage of an alternating current

Device that uses an electromagnet to measure electric current

A direct current is an electric current that reverses its direction of flow in a regular pattern

An alternating current is an electric current that reverses its direction of flow in a regular pattern
