The energy that is stored in an object or system is referred to as __________ energy.

Back

potential energy

Front

What happens to the potential energy in the system of magnets when a magnetic toy train is moved away from a stationary magnet?

Back

The potential energy increases because the train moves against the magnetic force.

Front

What is the term for the force that attracts or repels magnetic materials?

Back

magnetic force

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is a magnetic pole?

Back

The regions of a magnet where the magnetic force is strongest, typically labeled as north and south.

Front

What is the principle of magnetic induction?

Back

The process by which a changing magnetic field can induce an electric current in a conductor.

Front

What is the role of magnetic fields in electric motors?

Back

Magnetic fields interact with electric currents to produce motion.
