Question
In a commercial electric generator, the two permanent magnets are replaced with
- Soft iron pieces
- Single bar magnet
- Horseshoe magnets
- Electromagnets
Hint:
The two fixed magnets of the commercial generators are replaced by electromagnets.
The correct answer is: Electromagnets
In a commercial electric generator, the two permanent magnets are replaced with electromagnets.
- The permanent magnets in the commercial electric generator are replaced with electromagnets.
- The electromagnets create an emf in the coil and magnet.
- This induces current flow in commercial electrical generators.
