(a) Arigid circular loop of radius ‘r’ & mass ‘m’ lies in the ‘xy’ plane on a flat table and has a current ‘I’ flowing in it.At this particular place, the earth’s magnetic field is Vector B =Vector Bx i + Vector By j. How large must ‘I’be before one edge of the loop will lift from table ?
(b) Repeat if, Vector B = Vector Bx i + Vector By K.
