hcv: square loop thingy

JEE Advanced 2015 Discussion Forum › Electricity and magnetism questions › hcv: square loop thingy

In a region the magnetic field is B=B_o(1+x/l).
A square loop of side l through which a current i flows is placed in the region. What is the net magnetic force experienced by the loop ?

Force on AB = i B_o l
Force on CD = i B_o l
Force on BC = 2 i B_o l
Force on AD = i B_o l

Therefore Net magnetic force = i B_o l
