Question

In the figure, a conducting ring of certain resistance is falling towards a current-carrying straight long conductor. The ring and conductor are in the same plane. Then the

• A. induced electric current is zero
• B. induced electric current is anticlockwise
• C. induced electric current is clockwise
• D. ring will come to rest

Answer 1

The Correct Option is C

Step 1: As the conducting ring falls towards the current-carrying conductor, a change in magnetic flux occurs due to the changing distance between the ring and the conductor.
Step 2: According to Lenz’s Law, the induced current in the ring will flow in such a direction as to oppose the change in flux.
In this case, the magnetic flux increases as the ring moves towards the conductor, and to oppose this, the induced current in the ring will flow in the clockwise direction.
 Step 3: Hence, the induced electric current is clockwise.
