A metal rod is connected to a battery through two stiff metal wires that hold the rod horizontally. The rod is between the poles of a horseshoe magnet that is sitting on a mass-measuring platform scale, which reads 100.0 g. After you turned on the current in the circuit, the scale supporting the magnet read 106.0 g. The part of the rod that is exposed to the magnetic field is 6.0 cm long and the current through it is 2.0 A. Part A Find the magnitude of the magnetic field.
