A current of 8 amps runs in the +y direction on the y axis. Another current runs in the -y or +y direction 0.1 meters to the left of the y axis. A point charge of -8 coulombs is moving at the 2 m/s in the -x direction at a point which at x = +2.1 m, y = 0. The magnetic force on the charge due to the total magnetic produced by is 18 micro-Newtons in the + y direction. What is the amount of the force per unit length on the wire with 8 amps in micro-Newtons/m?

    A Long wire runs along the x-axis with a current of 3.2A, with the current in the -x direction. A circular loop of wire is placed directly on top of the wire with the loop in the x-y plane. This loops has a radius of 0.30 m with a counter-clockwise current of 0.67 A. Calculate the net magnetic field at a distance 0.21 m directly above the center of the ring (calculate in vector form).
