Magnetic Effects Of Electric Current
Draw a labelled diagram of an electric motor. Explain its principle and working. What is the function of a split ring in an electric motor?
An electric motor converts electrical energy into mechanical energy.
It works on the principle of the magnetic effect of current. A current-carrying coil rotates in a magnetic field. The following figure shows a simple electric motor.
When a current is allowed to flow through the coil MNST by closing the switch, the coil starts rotating anti-clockwise. This happens because a downward force acts on length MN and at the same time, an upw…
