Verified by Experts

The correct answer is:

.
the net magnetic force on a closed loop is
P.E

Here, direction of and is opposite.
P.
P.E.
that is (i)

Here, in the case,

So, is max is max i.e. (ii)
i.e. (i)
P.E in this case

(iii)

i.e. (i)

angle between and is

So,
So, P.E is positive i.e. (iv)
