Question
If a copper ring is moved quickly towards the south pole of a powerful stationary bar magnet, then:
- Voltage in the magnet increase
- Current flows in the magnet
- Current flows through the copper ring
- Copper ring will get magnetized
Hint:
If a copper ring is moved close to the south pole of a powerful stationary bar magnet, magnetic flux linked with the ring changes. Thus current flows through it.
The correct answer is: Current flows through the copper ring
If a copper ring is moved quickly towards the south pole of a powerful stationary bar magnet, then the current flows in the copper ring.
- The electromagnetic induction and the potential difference of the current depend on the speed of the coil or magnet moved closer to one another.
- If a copper ring is moved quickly towards the south pole of a magnet, there will be an emf formed.
- Thus the magnetic flux linked with the ring changes and current flows through the copper ring.
