____ law states that an induced voltage or current opposes the motion that causes it.
A)Edison's
B)Brush's
C)Fleming's
D)Lenz's

Question

Quizplus · Accepted Answer

Lenz's law states that an induced voltage or current always creates a magnetic field that opposes the magnetic field that caused it. This law follows the principle of conservation of energy, which states that energy cannot be created or destroyed, only transferred. Thus, when a change in magnetic field creates voltage or current in a conductor, Lenz's law ensures that the energy is conserved by opposing the initial change that caused it.
