    Question

    A magnet is moved towards a coil (i) quickly (ii) slowly. The induced potential difference is ____.

    1. More in (i) than in (ii) case
    2. More in (ii) than in (i) case
    3. Same in both
    4. Can’t say

    Hint:

    The induced potential difference of the current in a field depends on the speed at which the magnet is moved to it.

    The correct answer is: More in (i) than in (ii) case

      The induced potential difference is more in (i) than in (ii).
      • The induced potential difference of the current in a field depends on the speed at which the magnet is moved to it.
      • If the magnet moves quickly, the potential difference in current will be more.
      • When the magnet is moved slowly, the potential difference will be dropped and become less.
      • Thus, the potential difference of a current in an emf will be more when the magnet is moved quickly than it is moved slowly.
