PHXII06:ELECTROMAGNETIC INDUCTION

358706 Assertion :
Only a change in magnetic flux will maintain an induced current the coil.
Reason :
The presence of large magnetic flux through a coil can maintain an induced current if circuit is continuous.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

358707 A long solenoid of radius \(R\) carries a time \((t) - \) dependent current \(I(t) = {I_0}t(1 - t)\). A ring of radius \(2R\) is placed coaxially near its middle. During the time interval \(0 \leq t \leq 1\), the induced current \(\left(I_{R}\right)\) and the induced \(\operatorname{EMF}\left(V_{R}\right)\) in the ring change as -

1 Direction of \(I_{R}\) remains unchanged and \(V_{R}\) is maximum at \(t = 0.5\)
2 At \(t = 0.25\) direction of \(I_{R}\) reverses and \(V_{R}\) is maximum
3 Direction of \(I_{R}\) remains unchanged and \(V_{R}\) is zero at \(t = 0.25\)
4 At \(t\) \(=0.5\) direction of \(I_{R}\) reverses and \(V_{R}\) is zero
