According to Lenz's law in electromagnetic induction, the direction of the induced current is such that it:
A. Assists the magnetic flux change that produces it
B. Opposes the cause that produces it✓ Correct Answer
C. Remains independent of the magnetic field
D. Increases the total energy of the system
💡 Solution & Explanation
Lenz's law states that the polarity of the induced electromotive force and the direction of the induced current are always such that they oppose the change in magnetic flux that produces them, adhering directly to the principle of conservation of energy. Incorrect choices propose that the induced current assists or remains independent of the magnetic field change.
