Ch.20 Induced voltages and Inductance Faraday`s Law
... Now the conductor is part of a closed loop. See pictures on page 667. Conducting bar of length L slides along two fixed parallel conducting rails. Let the stationary part of the loop have a resistance R. A uniform and constant B-field is perpendicular to the plane of the loop. As the bar is pulled ...

ElectroMagnetic Induction
... A railgun consists of two parallel metal rails (hence the name) connected to an electrical power supply. When a conductive projectile is inserted between the rails (from the end connected to the power supply), it completes the circuit. Electrons flow from the negative terminal of the power supply up ...
