The magnet moving past an object will produce eddy currents in the object if the object:
A)is magnetic material only.
B)is a conductor.
C)is an insulator.
D)is a liquid.

Question

Quizplus · Accepted Answer

Eddy currents are induced electrical currents that are generated in conductive materials as a result of a changing magnetic field. Therefore, the object must be a conductor in order for eddy currents to be produced. Magnetic materials alone will not produce eddy currents, while insulators and liquids may not be conductive enough to allow for significant eddy current production.
