Question

In Activity 13.7 (page: 230), 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?

Answer 1

The displacement of rod AB is increased due to magnetic force exerted on it, if :

(i) If the current in the rod is increased then rod will be deflected with greater force.

(ii) If a stronger horse-shoe magnet is used then also rod will be deflected with greater force due to the increase in magnetic field.

(iii) If the length of the rod AB is increased.
