Which statement about eddy currents is false?
A)They can be prevented by cutting a slot in a solid conducting plate, to prevent electrons from being able to make a complete circuit.
B)The mechanical energy that is lost when eddy currents are created returns when the eddy currents cease.
C)They can be used as a passive braking system, as no external power source is needed if permanent magnets are used.
D)They are created in solid conducting plates as they move in and out of magnetic fields.
E)The faster the conductor moves, the larger the eddy currents will be.

The statement that mechanical energy lost when eddy currents are created returns when the eddy currents cease is false. Eddy currents create heat as they interact with the conductive material, which results in a net loss of energy.
