... An object travels from point A to point B while two constant forces of equal magnitude, and , are exerted on it. Think about the work done by each force and the net work. Is the magnitude of the velocity of the object at point B greater than, less than, or equal to the velocity of the object at poin ...

... Electromagnetic force is one of the four fundamental forces of the universe. It is a force that involves the interactions between electrically charged particles that occur due to their charge and for the emission and absorption of photons. An electromagnetic force generates an electromagnetic field, ...

... Faraday’s law for a coil • A commercial alternator uses many loops of wire wound around a barrel-like structure called an armature. • The resulting induced emf is far larger than would be possible with a single loop of wire. • If a coil has N identical turns and if the flux varies at the same rate ...
