1. The split ring in the electric motor is a commutator. The commutator reverses the direction of current flowing through the coil after each half rotation of the coil. Due to this direction of current getting reverse, the coil continues to rotate in the same direction.

  2. The different ways to induce current in a coil are as following: a. If a magnet is moved relative to a coil, then an electric current is induced in the coil. b. If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil.
