Q.
Assertion: Deflection of the iron filings changes when current in the conductor varies.
Reason: Magnitude of the magnetic field does not change with the magnitude of current.

1 Both assertion and reason are correct and reason is the correct explanation of assertion.

2 Both assertion and reason are correct, but reason is not the correct explanation of assertion.

3 Assertion is true, but reason is false.

4 Assertion is false, but reason is true.

Ans.
(3)

As the current changes in the conductor, magnitude of the magnetic field produced also varies which is the reason for a change in the deflection of the iron filings. Thus assertion is true, but reason is false
