Ai'g At bar sliding to the right. After an arbitrary time interval At passes the rod slides a displacement Ax as modeled below. As a result of that motion, the magnetic ux changes Explain how the change in magnetic ux can be quantitatively modeled by the expression AQB = BlAm. a. This circuit is able to generate electrical energy because of Faraday's Law Em = . The magnetic ux of the above circuit is able to change as a result of the b. Show that the induced EMF has a magnitude is given by Ema = BLT). c. At what speed should the bar move to achieve a current of 8.50 111A? Explain your conclusion. d. In what direction is the ow of the induced current? Explain how you determined it. a. How much power is dissipated by the resistor? Explain your conclusion. f. How far must the bar slide to produce 1.00 J of energy? Explain your work. Recall that a generator is a device that takes mechanical work and converts it into electrical energy. The circuit below is an example of such a device. A conducting bar of length l = 0.350 m is pushed to the right and slides on two frictionless conducting rails. A magnetic eld is present and directed into the page with a magnitude B = 0.300 T. Assume that the only resistance present is that of the resistor R = 9.00 n, the rails and sliding bar have negligible resistance
