The figure shows a rod of length L 9.35 cm that is forced to move at constant speed v 7.03 m/s along horizontal rails. The rod, rails, and connecting strip at the right form a conducting loop. The rod has resistance 0.472 ; the rest of the loop has negligible resistance. A current i 149 A through the long straight wire at distance a 9.44 mm from the loop sets up a (nonuniform) magnetic field throughout loop. Find the (a)...

3. Electromagnetic Inductance. Consider a single loop under magnetic field. (a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...
The conducting rod shown in the figure has length L and is being pulled along horizontal, frictionless, conducting rails at a constant velocity. The rails are connected at one end with a metal strip. A uniform magnetic field, directed out of the page, fills the region in which the rod moves. Assume that L 8.3 cm, the speed of the rod is v = 4.4 m/s, and the magnitude of the magnetic field is B = 1.0 T. (a) what...
A conducting rod is pulled horizontally with constant force F= 4.80 N along a set of rails separated by d= 0.620 m. A uniform magnetic field B= 0.500 T is directed into the page. There is no friction between the rod and the rails, and the rod moves with constant velocity v= 6.60 m/s. A.) Using Faraday's Law, calculate the induced emf around the loop in the figure that is caused by the changing flux. Assign clockwise to be the...
* Question 8 Your answer is partially correct. Try again. The figure shows a rod of length L = 14.8 cm that is forced to move at constant speed v = 5.17 m/s along horizontal rails. The rod, rails, and connecting strip at the right form a conducting loop. The rod has resistance 0.597 12; the rest of the loop has negligible resistance.

A metal crossbar with resistance R lies across conducting rails in a constant magnetic field B pointing out of the page as shown. The bar is moving at a speed v as indicated to the right. The rails have negligible electrical resistance compared to the crossbar, and you may neglect friction in the sliding of the crossbar.
