1. The physics of the force on a square coil of wire in a magnetic field. A square coil of wire containing a single turn is placed in a uniform 0.25 T magnetic field, as the drawing shows. Each side has a length of 0.32 m, and the current in the coil is 12 A. The direction of the current is clockwise. Determine the magnitude and direction of the magnetic force on each of the four sides. B d The physics of magnetic forces between two current carrying parallel wires. 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. . 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
