(13%) Problem 7: A wire bent into a rectangle with sides a=0.085 m and b = 0.045 m, is in a magnetic field B directed perpendicularly to the face of the wire, as shown. The perpendicular component is a function of time as B(t) = Asin(mt), where A = 0.45 T. = 1 rad s. In this problem, take the normal vector to the surface of the loop to be parallel to the magnetic field B 1111
