B 00200 T is in the positive y direction Determine t the mag
     B 0.0200 T is in the positive y direction. Determine t the magnitude and direction of the magnetic force on each segment. (Please give the ab 
  Solution
For ab, F = i L x B = 0 N because B and L are parallel (180 degree between them). Direction is not applicable as it zero.
For bc, F= i L x B = 4.7*0.36 * 0.02 = 0.03384 N towards -x direction
For cd, F= i L x B = 4.7*0.36*sqrt 2 * 0.02 *1/sqrt 2= 0.03384 N towards -z direction
For da, F= i L x B = 4.7*0.36*sqrt 2 * 0.02 = 0.04785 N towards right or xz direction
