A square loop ABCD of side length a and mass m is kept in a uniform magnetic field region B B as shown in the figure The loop is constrained to rotate only about the y axis It rotates only due to the torque of the magnetic force acting on it Calculate its angular speed when it has rotated through an angle 90 Initially the loop was lying in the x y plane The loop is carrying a current I as shown in the figure 31B Given O
