PROBLEM 1. [35 points] A long straight wire carries a current I. The wire is placed in a plane. A rectangular loop is also in the same plane, as shown in the figure at right. Let the z-axis point in the direction of I, and let the wire coincide with the z-axis. a) What is the total flux of the magnetic field from the current-carrying wire that passes through the rectangular loop?

(c) At t = 0, the current / begins decreasing as I = loea, where a is a positive constan Derive an expression for the magnitude of the emf & induced in the square loop AND indicate the direction (i.e., clockwise or counterclockwise in the figure shown above) of that emf E. Be sure to indicate how you determined the direction. (10 points)
