Magnetic flux  The more field lines you cut through in this picture, and the faster you do it, the larger the current that you produce  As can be seen, you must keep the wire or field moving relative to each other to generate an EMF  The wire must be cutting through the field lines or no current is generated if the wire is going parallel to the field lines  Current produced relative motion between the wire and field is known as an induced current o The phenomenon is known as electromagnetic induction
