An electric motor uses electromagnetism for its working. An electromagnet is installed in it instead of a permanent magnet. A current carrying wire produces a magnetic field around it and this is the principle on which an electric motor works.1.

Identify where are electric motors used in the following?a. Refrigeratorb. Electric cranec. Rolling millsd. All of the above3. On which principle does an electric motor works?a. Electromagnetismb. Frictionc. Chemical energyd. Muscular force4. Which of the following are the parts of an electric motor?a. Brushesb. Armature coilc. Both A and Bd. None of the above5. What will happen if armature coil is removed from the electric motor?a. More magnetic field will be producedb. Efficiency of the motor will be doubledc. Efficiency of the motor will be halvedd. The electric motor will not work
