PHY 102 Electromagnetic Induction Objective Question
Take CBT

Question

What does Lenz's Law state?
Options
A The induced current flows in the same direction as the change in flux
B An induced current will be in such a direction as to produce a magnetic field that opposes the change in flux that produced it
Correct Answer
C The induced emf is proportional to the square of the flux change
D The magnetic field always increases when a current is induced
Correct Answer

Option B is the correct answer.

Detailed Explanation

Lenz's Law states that the direction of the induced current opposes the change in magnetic flux that caused it. This is the negative sign in Faraday's Law.

Hint

Opposition to the change.
