Amplify Magnetic Fields Review

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

• The energy used to move a magnet with (same direction as) a magnetic force.
• The energy used to move a magnet against (opposite direction as) a magnetic force.
• Magnets get their potential energy from kinetic energy.
