Physics 43 Chapter 29 Homework 4. A loop (1.5cm x 3.0cm) is pulled at a speed of 3.00m/s out of a uniform B-field, IE I = 2.4 T. If the resistance of the loop is 0.60, what force (magnitude and direction) does the | is not B-field exert on the loop while a portion of the loop still exists in the field (i.e., zero)? 5. A conducting bar of 0.35m in length moves to the right. Let the resistance of the resistor be 9.000. a. If || = 0.3 T, what speed should the bar move to generate an 8.5mA current in the resistor? b. What is the direction of the induced current? c. What power is dissipated in the resistor? 6. Symbolic Solve: A square coil with N turns, side length L, and resistance R is moving with constant speed in a uniform B-field. At t = 0 , the coil has just begun to leave the B- field. At some later time, t', the coil has completely exited the field. a. Find the induced emf (magnitude only) in the loop from time t = 0 to t = t' b. Find the induced current (magnitude and direction) in the loop c. Find the power delivered in the coil d. Find the force (Fapp) required to push the coil at a constant speed
