A rectangular wire loop of 100 turns is used to pick up the signal generated from a car antenna. The antenna can be modeled as an infinite wire carrying a time-varying current () = 2sin(109) A, upward at t = 0 . Treat this as a simple 2-dimensional problem; i.e, the rectangular loop and the car antenna are both lying flat on this page as shown. At t = 0, the antenna is 300 m from the edge of the loop as shown in the diagram. The car is moving at 36 kph to the left. What is the amplitude of the induced current in the loop at t = 0 (in mA)? What is the direction of the induced current? Explain, using Lenz's Law. The "resistivity" of the wire loop is 0.3 m
