A 1.10-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform, 0.790-T magnetic field. The bar rides on parallel metal rails connected through R = 25.5-Ω, as shown in the figure (Figure 1), so the apparatus makes a complete circuit.

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 0.204 m -long bar moves on parallel rails that are connected
through a 6.05 Ω resistor, as shown in the following figure (Figure
1), so the apparatus makes a complete circuit. You can ignore the
resistance of the bar and rails. The circuit is in a uniform
magnetic field 1.45 T that is directed into the plane of the
figure. At an instant when the induced current in the circuit is
counterclockwise and equal to 1.70 A , what...
A proton moves perpendicular to a uniform magnetic field B at a speed of 1.70 times 10^7 m/s and experiences an acceleration of 1.90 times 10^13 m/s^2 in the positive x direction when its velocity is in the positive z direction. Determine the magnitude and direction of the field. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to...
