Question
A magnet is moved towards a coil (i) quickly (ii) slowly. The induced potential difference is ____.
- More in (i) than in (ii) case
- More in (ii) than in (i) case
- Same in both
- 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.
