Assertion (A) : It is more difficult to push a magnet into a coil with more number of turns.
Reason (R) : The emf induced in a coil opposes the motion of a magnet when it is moved towards the coil.
- A A is false, R is true
- B Both A and R are true. R is correct explanation of A
- C A is true, R is false
- D Both A and R are true. R is not correct explanation of A
Answer & Solution
Correct Answer
(B) Both A and R are true. R is correct explanation of A
Step-by-step Solution
Detailed explanation
(A) It is more difficult to push a magnet into a coil with large turns because of opposition caused by induced current. (B) The emf induced in a coil always opposes the motion of a magnet when it is moved towards the coil. It was experimentally verified by lenz law. So both…
