Question

In commercial electric motors the coil is wound on a _________ core.

  1. Plastic
  2. Aluminium
  3. Copper
  4. Soft iron

hintHint:

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.
