Question

8.) (30 points) A rectangular frame of conducting wire has negligible resistance and a width 1.0 m is placed in a magnetic field (directed into the page) of 2.0 T, as shown in the figure A metal conducting bar having a resistance of 5.0Ω is placed across the frame, maintaining contact with the frame. conducting frame rod If the bar is moving at a speed of 1.5m/s, what is the voltage (em) induced across the ends of the bar? a) b) Which end of the bar has the higher potential? What is the value of the current flowing through the circuit made by the frame and rod? c) Now, the frame is turned upright as shown below and the rod is at rest. Also, in addition to the rod having a resistance of 5 2, we are given that it has a mass of 2 kg. Xm rod xxXxxxx x conducting x frame x xxx x d) If the rod is allowed to fall freely along the frame starting from rest and friction is negligible, determine the terminal velocity (v) of the rod. (Hint: Terminal velocity is reached when the net vertical force on the rod is equal zero.) After the rod has reached maximum velocity, determine the electrical power dissipated by the moving rod e)
