Unformatted text preview: motional emf is proportional to the speed of the rod, the length (L) of the rod, and the magnetic field: If the metal rod is part of a complete circuit, the induced emf will cause a current to flow. Because it's in a magnetic field, the rod experiences a force because of the interaction between the field and the current. This force always acts to oppose the motion of the rod. When we looked at DC motors, we saw how the force exerted on a current flowing around a coil in a magnetic field can produce rotation, transforming electrical energy to mechanical energy. Motional emf is a good example of how mechanical energy, energy associated with motion, can be transformed to electrical energy....
