Question

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

Explanation / Answer

option (B) will be false because eddy current is a circulating current generated on the surface of conductor due to variation of magnetic flux. hence a localized e.m.f. and thus a circulating current produced as a result of this if due to surface resistance of the conductor the energy loose and appear in form of heat and hence it warmed the surface or gone to the atmosphere so it never return back .
