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.
Options
- AA is false, R is true
- BBoth A and R are true. R is correct explanation of A
- CA is true, R is false
- DBoth A and R are true. R is not correct explanation of A
Correct answer
B. Both A and R are true. R is correct explanation of A
Step-by-step solution
(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 and are true. is correct explanation of .
