Physics 4B - Chapter 29 Homework 1. A solenoid with radius 0.04m and 500 turns is connected to a 600 resistor and is subject to the time-varying magnetic field B(t) = 0.012t + (3x10-5)t4. The central axis of the solenoid is parallel to the B-field. a. Find the induced emf (magnitude only) as a function of time. b. What is the current in the resistor at t = 5.0sec? 2. A loop of wire (r = 4.8x 10-2m) is placed in a varying B-field. Initially, B(0) = 8.0T and the B-field decreases according to o = db = -0.68-. a. Determine the direction of the inducted current in the loop (cw or cow) b. If the resistance in the loop is 0.160, determine the power that is dissipated in the loop. 3. Determine the direction of the induced current for pictures A - F. (a) (D) (C) (d) B increasing B decreasing (e)
