Question

On which principle does electric motor work

Answer 1

Answer:

The electric motor works on the principal that the current carrying conductor placed perpendicular to the magnetic field experiences a mechanical force.

This force can be determined by Fleming's left hand rule.

Hope this will be helpful

Good Luck!

Answer 2

Answer:

The electric motor works on the principle of magnetic effect of electric current.

When current is passed through a coil of many circular loops, armature coil; then, due to the magnetic effect of electruc currrent, magnetic field around it is induced.

This results in the coil to experience a couple of equal and opposite forces, constituing a torque and thus rotating the coil along it axis.

This is based on Fleming's Left hand rule
