Question

Lenz' law states that the direction of the induced emf and hence current
Options
A is determined by the rate of current flux
B is found by the right hand rule
C is found by the left hand rule
D always opposes the cause producing it
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Lenz's law is essentially a statement of conservation of energy: the induced current always flows in a direction that opposes the change in flux that created it.

Hint

Recall that Lenz's law is about opposition, not about a hand rule (that's for direction of force/field, not this statement).
