A magnetic field is created by the movement of electric charges through metal. The existence of a magnetic field creates a real force that influences its surroundings. This force depends on the direction of the current and the field (the direction of the field lines) and their intensity. There are a few simple rules for determining the direction of this force. In fact, you can see it simply by using your hand. The video demonstrates the force and shows how to identify its direction.
