Part of a single rectangular loop of wire with dimensions b=0.750m along the x dir., l=0.350m along the y direction is situated in the xy plane inside a region of uniform magnetic field of 0.650 t pointing in neg z direction (into the board) . the total resistance of the loop is calculate the force required to pull the loop from the field (to the right in pos x dir) at a constant velocity of the neglect gravity.
