Assertion (A): Only a change in magnetic flux will maintain an induced current in a closed coil.
Reason (R): The presence of large magnetic flux through a coil maintains a current in the coil if the coil is continuous.

Solution

The correct option is C A is true but R is false
$E M F = - \frac{d ϕ}{d t}$
So, change in flux produces EMF which in turn produces current provided cirucit is closed.
EMF is produced by small magnetic changing flux also.

Assertion (A): Only a change in magnetic flux will maintain an induced current in a closed coil.Reason (R): The presence of large magnetic flux through a coil maintains a current in the coil if the coil is continuous.

The correct option is C A is true but R is falseEMF=−dϕdtSo, change in flux produces EMF which in turn produces current provided cirucit is closed.EMF is produced by small magnetic changing flux also.
