For Lab #7, a wire segment is placed between the poles of a magnet with the segment perpendicular to magnetic field. The magnet is placed on a scale such as to measure the magnetic force produced. The scale reads O.00 g when no current passes through the wire. The length of the wire segment is 2.0 cm. When a 2.0 A current passes throught the wire, the scale reads 0.45 g. What is the strength of the magnetic field in mT? (Hint: The magnetic force will be mg, where m is the scale reading.)
