Question
In commercial electric motors the coil is wound on a _________ core.
- Plastic
- Aluminium
- Copper
- Soft iron
Hint:
Soft iron increases the strength of magnetic field
The correct answer is: Soft iron
In commercial electric motors: i. the coil is wound on a soft iron core. This increases the strength of magnetic field which makes the motor more powerful.
