A force is exerted when a current passes at through a magnetic field with a right (90 degree) angle. If an external magnetic field is present, the field produced wiil repel as the force is experience by the conductor. Such phenomena leads to movement. The direction of force can be determined using the traditional Flemmings Left hand Motor rule which can be represented using our left hand.
