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:-

(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.
