Electromagnetic Forces Vocabulary

Flashcards covering key vocabulary terms related to electromagnetic forces and their definitions.

magnet

An object that attracts iron and other materials that have magnetic qualities similar to iron.

magnetic force

A force of attraction or repulsion created by a magnet.

magnetic pole

The place on a magnet where the force it exerts is the strongest.

magnetic potential energy

Stored energy due to the interactions of magnetic poles in a magnetic field.

magnetic domain

Region in a magnetic material in which the magnetic fields of the atoms all point in the same direction.

electric field

The invisible region around a charged object where an electric force is applied.

electrically charged

The condition of having an unbalanced amount of positive charge or negative charge.

electrically neutral

A particle with equal amounts of positive charge and negative charge.

induction

Charging an object without touching it.

electric insulator

A material through which electrons cannot easily move.

conduction

The transfer of charged particles between two conductors.

electromagnetism

The interaction between electric charges and magnets.

electromagnet

A magnet created by wrapping a current-carrying wire around a ferromagnetic core.

electric motor

A device that uses an electric current to produce motion.

electric generator

A device that uses a magnetic field to transfer mechanical energy to electric energy.

current

The movement of electrically charged particles.

direct current

An electric current that continually flows in one direction.

alternating current

An electric current that changes direction in a regular pattern.

closed circuit

A circuit that is complete and electric energy flows through the circuit.

open circuit

A circuit that is not complete and no electric energy flows through the circuit.

voltage

The electrical potential energy difference between two places on an electric circuit.
