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

  1. AA is false, R is true
  2. BBoth A and R are true. R is correct explanation of A
  3. CA is true, R is false
  4. 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 A and R are true. R is correct explanation of A .
