Physics Moving Charge and Magnetism Statement Based MCQ (Single Correct)

Statement I: If we consider two wires carrying currents I 1 and I 2 , then for the Amperian loop shown

Then, , even when the second wire is present or not.
Statement II: At some points magnetic fields of both wires oppose each other and add up at some points and so, in sum over complete path these effects balance each other.
In the light of the above statements, choose the most appropriate answer from the options given below.

Both Statement I and Statement II are incorrect.

Statement I is correct but Statement II is incorrect.

Both Statement I and Statement II are correct.

Text Solution

Verified by Experts

The correct answer is:

Both Statement I and Statement II are correct.

In the magnetic field exists due to both wires whereas is current enclosed.
At some points of path enclosed, and at some points and when we sum , these effects balance each other and sum does not have effect of . So, with or without the other wire.
