A metal rod is connected to a battery during two stiff metal wires that hold the rod horizontally. The rod is among the poles of a horseshoe magnet that is sitting on a mass-measuring platform scale, which reads 100g. After you turned on the current in the circuit, the scale supporting the magnet read 106 g. The rod is 7.0 cm long and the current through it is 1.4A.

Discover the magnitude of the magnetic field.
