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...
A long straight wire carrying a current of 2.03 A moves with a constant speed v to the right. A 120 turn circular coil of diameter 1.50 cm, and resistance of 3.25 u 2, lies stationary in the same plane as the straight wire. At some initial time the wire is to the left of the coil at a distance d = 13.0 cm from its center. 5.00 s later, the wire has moved to the right of the coil...
