The best example for changing the rotation due to torque is the bar magnet which rotates under the magnetic field. In this case, the magnetic field is the external force which changes the north and south pole of bar magnet to show the direction in sea.

Answer 2

Answer:

A body rotates when there is a net torque acting on it.To change the direction of rotation of a rotating body with fixed axis we will have to provide a retarding torque which will ultimately stop the rotation and will start it in the opposite direction. As a result the direction of rotation of the body will change.
