A long straight wire carries a current that travels in the negative j direction and INCREASES at a rate of dI/dt. The wire is in the same plane as a rectangular loop of width "a" (where "a"

a) [6 points] What is the rate that the magnetic field increases at a distance, "x", from the wire?

b) [6 points] What is the direction of the magnetic field that the long wire creates in the middle of the rectangular loop (circle your answer)?

+i -i +j -j +k -k

c) [6 points] What is the direction of the INDUCED magnetic field in the MIDDLE of the wire loop (circle your answer)?

+i -i +j -j +k -k

d) [6 points] What is the direction of the INDUCED current in the wire loop that creates this INDUCED magnetic field? (circle your answer)

clockwise counterclockwise e) [6 points] What is the magnitude of the induced EMF around the loop?
