A rectangular loop of wire of width w and length and a long straight wire carrying a current are arranged as shown on the attached phys241 Ex4 1 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 = a + bt, determine the EMF induced in the loop. Assume thatb= 5A/s, d = 2.0 cm, w = 15 cm, i = 150 cm. c} Determine the direction of the induced current in the loop.
