Question

Assertion (A): Whenever the magnetic flux linked with a closed coil changes there will be an induced emf as well as an induced current.
Reason (R): According to Faraday, the induced emf is inversely proportional to the rate of change of magnetic flux linked with a coil.

• A. Both A and R are individually true and R is the correct explanation of A
• B. Both A and R are individually true but R is not the correct explanation of A
• C. A is true but R is false
• D. Both A and R are false

Answer 1

The correct option is C A is true but R is false

$EMF=-\frac{d\varphi }{dt}$
So, EMF is directly proportional to the rate of change of magnetic flux linked with a coil. When closed coil is used current flows into it.
