Question

24. A conducting circular loop of radius r carries a
constant current / It is placed in uniform magnetic
field B, such that B is perpendicular to the plane
of the loop. The net magnetic force acting on the
loop is
(1) irB
(2) 2πriB
(3) Zero
(4) πirB

Answer 1

F = I (dl× B)

so the answer is 0

because the components cancel each other....

I hope it helps you ❤️
