Electromagnetic Fields and Forces

Electromagnet

• The area around a magnet or moving electric charge that can exert a magnetic force

• A device that changes mechanical energy into usable electrical energy

• The production of electric potential difference across a conductor as the conductor moves through a magnetic field.

• A temporary magnet where the magnetic field is produced by electric current

Electromagnetic Induction

• A device that transfers electrical energy from one circuit to another through electromagnetic induction

• A device that changes mechanical energy into usable electrical energy

• The production of electric potential difference across a conductor as the conductor moves through a magnetic field.

• A material that retains its magnetism after it is removed from a magnetic field and without an electric current flowing through it.
