Question

The magnetic field existing in a region is given by b

Answer 1

we know, Bx = Bo(1+x/l)k, and Bx+l = Bo(1- (x+l)/l)k. Now, Fx = i (l x Bx),

this implies, Fx = ilBxo (j x k) = ilBxoi = ilBo (1+x/l)i. Similarly, Fx+o = -ilBo (1+(x+l)/l)i.

Therefore, the net force = Fx + Fx+o = ilBo(1+x/l)i – ilBo (1+(x+l)/l)i.

Hence, the magnitude of the net force is ilBo.
