Question

Problem 3

Answer 1

Given information

When a current is induced in the loop.

 

Step-by-step explanation

Step 1.

Option (d.) as it passes line J or L, is the correct answer

A current is precipitated inside the loop only when the area within the magnetic field or the strength of the magnetic field or the angle between the magnetic field and area changes. Initially, when the loop is completely outside the region on left, no magnetic field passes through it, and as a result the loop has no magnetic flux. Because the loop crosses line J on left, the magnetic field lines start passing through the loop and consequently the loop gains magnetic flux. This transformation in magnetic flux reasons the current to be induced inside the loop.
