What is an electric generator?

Back

An electric generator is a device that uses a magnetic field to convert mechanical energy into electrical energy.

Front

What is a force?

Back

A force is a push or pull exerted on an object.

What is a magnetic domain?

Back

A magnetic domain is a region in a magnetic material where the magnetic fields of the atoms all point in the same direction.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which electric energy can flow.

Front

What is the relationship between force and motion?

Back

Force is responsible for changing the motion of an object; it can cause an object to start moving, stop moving, or change direction.
