PHY 102 Electromagnetic Induction Objective Question

Question

If the magnetic flux through a loop is increasing to the left, what direction of induced current will oppose this change?
Options
A Clockwise
B Counterclockwise
Correct Answer
C No current
D Depends on the material
Correct Answer

Option B is the correct answer.

Detailed Explanation

By Lenz's Law, the induced current will create its own magnetic field opposing the increase. To oppose an increasing leftward field, the induced field must point to the right, which requires counterclockwise current (by right-hand rule).

Hint

Oppose the increase by producing opposite field.
