2. Two wires are running parallel to each other. Each wire carries a current of 4.0 A and each wire is 50.0 cm long. The magnetic field strength that the top wire produces at the location of the bottom wire is 8.0 T. I a. Determine the direction of the magnetic field at the location of the bottom wire caused by the top wire. b. Determine the magnitude and direction of the force on the bottom wire.
