Case : Read the passage and answer the question(s). Lenz's Law states that the polarity of induced EMF is such that it tends to produce a current which opposes the change in magnetic flux that produced it. Hypothetically or not, assume that on approaching the magnetic north pole towards a coil, the coil develops current in clockwise direction. |
Which of the following is true? |
This violates conservation of charge. This violates conservation of energy. This violates conservation of angular momentum. This does not violate anything. |
This violates conservation of energy. |
Lenz's Law is in agreement with conservation of energy and the given statement violates Lenz's Law. |
