What is created when a magnet moves through a coil of wire?

Back

An electric current is created when a magnet moves through a coil of wire.

Front

What is a solenoid?

Back

A solenoid is a coil of wire that generates a magnetic field when an electric current passes through it.

Front

What is the relationship between electricity and magnetism?

Back

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

Front

What is a magnetic field?

Back

A magnetic field is an invisible field around a magnet where magnetic forces can be felt.
