Question

A circular current loop of radius a is placed in a radial field B as shown. The net force acting on the loop is

  1. zero    
  2. 2 pi BaIcos invisible function application theta    
  3. 2 pi aIB s i n invisible function application theta    
  4. None    

The correct answer is: 2 pi aIB s i n invisible function application theta


    For radial component of magnetic field, the total force will be either in the upward or in the downward direction depending on the direction of current. \ Force equals I L B perpendicular equals I left parenthesis 2 pi a right parenthesis B s i n invisible function application theta
