A conducting current-carrying plane is placed in an external uniform magnetic field. As a result, the magnetic induction becomes equal to `B_(1)` on one side of the plane and equal to `B_(2)` on the other side. Find the magnetic force acting per unit area of the plane in the cases illustrated in the figure.
