Front

What is the function of a motor?

Back

A motor converts electrical energy into mechanical energy.

Front

What is the function of a generator?

Back

A generator converts mechanical energy into electrical energy.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, often caused by the transfer of electrons.

Front

What is produced by moving a permanent magnet through a coil of copper wire?

Back

Electricity is produced.

Front

What happens when you run a current through a coil of wire?

Back

A magnetic field is created around the wire.

Front

How can you induce a current in a wire?

Back

By changing the magnetic fields, such as moving a magnet in and out of the wire.

Front

What is electromagnetic induction?

Back

Electromagnetic induction is the process of generating electric current in a conductor by changing the magnetic field around it.

Front

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interrelated; electric currents produce magnetic fields, and changing magnetic fields can induce electric currents.
