In Activity 13.7, how do we think the displacement of rod AB will be affected if (i) current in rod AB is increased; (ii) a stronger horse-shoe magnet is used

In a magnetic field, a current-carrying conductor experiences force. The magnitude of this force grows as the amount of current, the length of the conductor, and the strength of the magnetic field grow. As a result, the magnetic force exerted on the rod AB will get stronger and its displacement will increase if

(i) The current in rod AB is increased

(ii) Stronger horse shoe magnet is used
