← ScienceWhich outcome occurs when a strong external alternating magnetic field induces eddy currents inside a solid aluminum rotor?
A)Rotor achieves synchronized rotation✓
B)Harmonic resonance prevents movement
C)Dielectric breakdown insulates segments
D)Static charge accumulates unevenly
💡 Explanation
The rotor accelerates in the same direction as the rotating field because Lenz's law dictates the direction of the induced eddy currents, therefore the rotor turns rather than remaining stationary or accumulating charge due to inductance.
