Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The magnetic field B $\propto$ I (current through the loop) if I changes magnetic field changes. magnetic field due to a magnet and due to current is same, but both assertion and reason are the different conditions.
