Question.
In activity 13.7, how do we think the displacement of rod PQ will be affected if
(i) current in rod PQ is increased
(ii) a stronger horseshoe magnet is inserted
(iii) length of the rod PQ is increased.

(ii) a stronger horseshoe magnet is inserted
(iii) length of the rod PQ is increased.
solution:
(i) When current in rod increases, force on the rod also increases. Hence, the displacement of the rod increases.
(ii) When a stronger horseshoe magnet is inserted, magnetic field increases. Thus, force on the rod also increases. Hence, displacement of the rod increases.
(iii) When length of the rod increases, force on the rod also increases and hence, displacement increases.
