Question

Commercial electric motors do not use?

Answer 1

1. An electric motor operates based on the magnetic field created around the current-carrying wire.
2. A current-carrying conductor is placed perpendicular to the magnetic field, causing a force to be felt.
3. Copper wire is used to make the coil. It's because copper is such a good conductor. It's already being wound on an armature coil.
4. When a current flows through the coil, it transforms into an electromagnet.
5. The armature of an electric motor will not be constructed with a permanent magnet. Electromagnets are used instead.
6. A solenoid is used in commercial electric motors to rotate the armature.
7. This solenoid is also referred to as an electromagnet.
8. A strong magnetic field is created by whirling a large number of wire turns on a soft iron core.

Therefore, commercial electric motors do not use a permanent magnet to rotate the armature.
