MCQ
If the coil in a simple generator is wound around a soft iron core then:
- AStrength of magnetic field increases.
- BCurrent produced will be increased.
- CVoltage produced will be increased
- ✓All
✓
Answer
Correct option: D.
All
Voltage$/$ current produced in a generator can be increased by:
$(i).$ Using a powerful electromagnet to make the magnetic field stronger in place of a permanent magnet.
$(ii).$ By winding the coil round a soft iron core to increase the strength of magnetic field.
$(iii).$ By using a coil with more turns.
$(iv).$ By rotating the coil faster.
$(v).$ By using a coil with a larger area.
