Explain different ways to induce current in a coil


Q. What is the role of the split ring in an electric motor?

 

Answer:-

The different ways to induce current in a coil are as follows:
(i) Moving a magnet towards a coil sets up a current in the coil circuit,

 

(ii) If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil.
