What is a magnet?

Back

A magnet is an object that produces a magnetic field, attracting certain materials like iron.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the role of motion in generating electric current?

Back

For a magnet inside a wire loop to produce an electric current, the magnet must be in motion relative to the loop.

What is an insulator?

Back

An insulator is a material that does not allow electrons to move easily, preventing the flow of electric current.

Front

What is a conductor?

Back

A conductor is a material that allows electrons to move freely, enabling the flow of electric current.

Front

How does distance affect electric force?

Back

The electric force decreases as the distance between charged objects increases.
