Amplify Magnetic Fields Review

Front

What is potential energy?

Back

The energy that is stored in an object or system.

Front

How does a system of magnets store potential energy in the magnetic field?

Back

The energy used to move a magnet against (opposite direction as) a magnetic force.

Front

Which move will result in the greatest potential energy increase?

Back

Moving the cart on Track 2 one space to the right.

Front

What happens when two magnets with the same poles face each other?

Back

They repel each other.

Front

What happens when two magnets with opposite poles face each other?

Back

They attract each other.

Front

What are magnetic field lines?

Back

Imaginary lines that represent the direction and strength of a magnetic field.

Front

What is the relationship between magnetic field strength and distance from the magnet?

Back

The strength of the magnetic field decreases as the distance from the magnet increases.

Front

What is a magnetic force?

Back

The attraction or repulsion that arises between charged particles due to their motion.

Front

What is the role of kinetic energy in moving magnets?

Back

Kinetic energy is the energy of motion that can be converted to potential energy when moving a magnet.

Front

What is the difference between attraction and repulsion in magnets?

Back

Attraction occurs between opposite poles, while repulsion occurs between like poles.
