alleryIf the induced current helped the magnet instead, a gentle push would give endless speed. This breaks:
ACharge conservation
BNewton's third law
CHooke's spring law
DEnergy conservation
Answer & Solution
Correct answer: D. Energy conservation
1. The magnet would speed up for free.
2. That would be a perpetual motion machine.
3. It violates conservation of energy.
