EE1; Homework 7: DUE JUNE 5TH FRIDAY 5 PM (THERE IS A COLLECTION BOX NEAR MARIKO WALTON’S CUBICLE IN 66-127 ENGR IV ) (1) Two parallel, circular loops carrying a current of 40A each are arranged as shown in the Figure below. The first loop is situated in the x y plane with its center at the origin and the second loop’s center is at z = 2m. If the two loops have the same radius a = 3 m, determine the magnetic field at: a. z = 0 b. z = 1m c. z = 2m (2) An infinitely long wire carrying a 25-A current in the positive x -direction is placed along the x -axis in the vicinity of a 20-turn circular loop located in the x y plane as shown in the following Figure. If the magnetic field at the center of the loop is zero, what is the direction and magnitude of the current flowing in the loop?
