8.02 Lecture Notes - Lecture 1: Curve, Electric Potential, Surface Integral
Document Summary
While a rectangular wire loop is pulled upward through a uniform magnetic eld b eld penetrating its bottom half, as shown, there is a current in the loop. Product of perpendicular component of magnetic eld and area. Imagine a charge q moving around a closed path under the action of a force f. Then the work done per unit charge is called the electromotive force. Has the same dimensions as the electric potential so si unit is the volt. If the closed path is a circuit with resistance r then the electromotive force will cause a current to ow according to. Pull a loop with speed v through a uniform magnetic eld. While a rectangular wire loop is pulled sideways through a uniform magnetic eld b eld penetrating its bottom half, as shown, there is no current in the loop. Conducting rod pulled along two conducting rails in a uniform magnetic eld b at constant velocity v.
