Q. A hypothetical magnetic field existing in a region is given by B = B 0 e r where e r denotes the unit vector along the radial direction. A circular loop of radius a , carrying current , is placed with its plane || to the X - Y plane and the centre is at ( 0 , 0 , d ). Find the magnitude of the magnetic force acting on the loop. Is this physically possible ?

dear student,
Required magnetic force
F=∫dF=∫(_(0)2πaidlbsinsinthiηF=∫dF=∫(_(0)2πaidlbsinsinthiη
=iB,aa−−√2+d2∫2πa0dL=iB,aa2+d2∫02πadL
` = (2 pi a^(2) B /(sqrt a^(2) + d^(2) ).
hope it helped
