Physics Unit 6: E&MF&F Flashcards

Front

Conduction

Back

Transferring charge by contact (two items touch).

Front

Electric field

Back

A region of space characterized by the existence of a force generated by electric charge.

Front

Electric force

Back

An attractive or repulsive force that occurs between charged objects due to their electric charges.

Front

Electromagnet

Back

A coil of wire that temporarily becomes a magnet when an electric current flows through the wire.

Front

Generator

Back

A machine that produces electrical current by moving a coil of wire within a stationary magnetic field.

Front

Induction

Back

Transferring charge without contact (two items share a force field but do not touch).

Front

Magnetic field

Back

The area around a magnet containing all of the magnetic lines of force.

Front

Magnetic force

Back

The mechanical force exerted by a magnetic field on a charged particle or magnetic object.

Front

Motor

Back

A machine that converts electrical energy into mechanical energy using a stationary coil of wire and a moving magnet.

Front

Polarization

Back

Separating positive and negative charges by induction or conduction.
