Question

By using the given experimental set-up. How can it be shown that:

1. a force is exerted on the current-carrying conductor AB when it is placed in a magnetic field.
2. the direction of force can be reversed in two ways.

Answer 1

1. The Fleming’s left-hand rule states that the conductor experiences a force and travels in a specific direction. This movement shows that the interaction of the electric current and magnetic field exerts a force on the conductor.
2. 1. Changing the direction of the magnetic field.
   2. Changing the direction of an electric current.
