Question

Give two ways of reversing the direction of the forces on the coil in the electric motor?​

Answer 1

Answer:

Interchanging the poles of the magnet

Reversing the direction of the applied current

Explanation:

1. The working of the electric motor is associated with Fleming's left-hand rule.
2. It states that if a current-carrying conductor is placed inside a magnetic field, it experiences a force in the direction perpendicular to the direction of the electric current and magnetic field.
3. These three physical quantities are placed in a mutually perpendicular direction.
4. So, in order to reverse the direction of force, you have to either change the direction of the current or magnetic field.
