EE 311 Homework 10 Updated (Due Wednesday, April 13, 2011, Class time) Faraday’s Law-Electrodynamics, Displacement Current, Maxwell’s equations (5 questions) 1. (20 pts) 2. (20 pts) A 2m × 1m rectangular loop contains a 10 resistor and is moving at 1 m/s towards a region of uniform magnetic fields 10 T out of the page and of width 4 m. Assume the rectangular loop begins to enter the 4 m wide region of uniform magnetic field at t=0. Plot the current versus time in the 10 resistor from t = 0 to t = 7 s. Assume the current is positive if
