Assertion : Only a change in magnetic flux will maintain an induced current in the coil. Reason : The presence of large magnetic flux through a coil maintains a current in the coil if the circuit is continuous.
Options:
Answer:
C
Solution:
Induced current (emf) in a coil is directly proportional to the rate of change of magnetic flux linked with the coil. If there is no change in the flux, there is no induced current also.
