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?
(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.
