m, RU B2 8. An adjustable loop, with a cross-bar of width w that slides between two rails, is tilted so that it makes an angle with respect to the ground. Let the sliding cross-bar have a resistance R and a mass m (and neglect any other resistance). a. If the loop is placed in a vertical magnetic field, B = Bỉ, show that the cross-bar does not keep accelerating, but reaches a terminal speed mgR sine B2w2 cos20 V...

Group Problem 1. A conducting bar with mass m and resistance R slides on frictionless conducting rails, separated by a distance 1 from each other, in a region that has a static uniform magnetic field B directed into the page (see figure below). An external agent is pushing the bar, maintaing its motion to the right with constant velocity ū. At time t = 0, the agent abruptly stops...

1. An electron moves in a circular path in the magnetic field of an electromagnet. The plune of the electron's Sicular path is parallel to the smooth vole faces of the electromagnet. In the region where the electron is moving the magnetic field is uniform and has magnitude 0,50 T. The electron moves with a speed of 1.5 x 10 m/s. a. If someone could observe the electron from the north pole of the electromagnet, would the electron inove clockwise...
