Answer 2

Two electrical appliances of daily use in which electric motor is used:

Water pumps, washing machine.

Working principle of an electric motor:

An electric 'motor' is a "device" that basically converts 'electrical energy' into 'mechanical energy'. The main principle behind an electric motor depends on the magnetic effect caused by the electric current.

This principle-based on "Fleming’s left-hand rule" and is based on the fact that a current laden loop, when placed in a 'magnetic field', experiences a force in a direction 'perpendicular' to the 'magnetic field' and current.
