P.6-6 A conducting sliding bar oscillates over two parallel conducting rails in a sinusoidally varying magnetic field B a. 5 cos ot (mT), as shown in Fig. 6-12. The position of the sliding bar is given by x- 0.35(1- cos ot) (m), and the rails are terminated in a resistance R 0.2(2). Find i. 0.2 (m) FIGURE 6-12 A conducting bar sliding over parallel rails in a time-varying magnetic field (Problem P.6-6).
There is a magnetic field B = 0.5 T constant entering the paper. The conductive bar is of length l = 0.2 m, and moves to the right on conductive rails with velocity v = 10 m / s on conductor rails. R symbolizes a resistance of 10 W. 20. The current in the circuit is ____ 21. The power dissipated in R is ____ 22. And to maintain the current, pull the bar with a force F of ____
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...
