Make object point to cursor

Hi all,
I am creating a lesson for my class on the magnetic compass. I have placed a drawing of a compass on the stage. To add some interest I would like the compass needle (north end) to point in the direction to where the cursor is on the stage and “follow” it as it moves. The compass would remain in the same spot and only the compass needle rotate/move accordingly.

Any help in ‘heading me in the right direction’ would be appreciated.
