Answer 1

we know that magnetic moment is equal to N.i.a

where N = no. if turns.
I = current
a= cross section area.

here loop are at 90 degrees so we can't say that magnetic moment is 0.

*magnetic moment is zero for close loop but loop must be in same plane...

but in this question loops are in 3d-plane so both magnetic moment vector can't cancel each other.. therefore magnetic moment is not zero.

# if u want to find direction of magnetic moment then use right hand thumb rule
