A rectangular loop of wire of width w and length I and a long straight wire carrying a current I are arranged as shown on the attached figure. O a) Determine the magnetic flux through the loop due to the current in the long wire. b) If the current in the long wire varies with time as I(t) = a + bt, determine the EMF induced in the loop. Assume that b = 13 A/s, d = 5 cm, w = 20 cm, I = 75 cm. c) Determine the direction of the induced current in the loop.w
