In activity 13.7 (on page 234) 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 and (iii) length of the rod AB is increased.
(i) If current in rod AB is increased its displacement will increase. (ii) If a stronger horse-shoe magnet is used then the displacement of rod AB will increase. (iii) If the length of the rod AB is increased force acting on it will increase and the displacement of the rod also increases.
