Please solve this prob :- Q1 A circular wire-loop of radius a carries a current i and is placed in perpendicular magnetic field B. Find the force of compression in the wire. My answer coming to this is i (2 pi a) B. But, correct is iaB!! Also, net force on a current carrying closed loop in a tranverse magnetic field is 0. Then, how come above a non-zero value is coming.
