Two long wires cross at 90 degrees. The vertical wire carries a current of 6 A downward. The horizontal wire carries a 3 A current directed towards the right. a) Determine the direction of the magnetic field at Point P, a distance of 6.0 c from each wire.
b) Determine the magnitude of the net magnetic field at point P.
c) Assume that a single electron was placed at point P and given a velocity of 2x10^6 m/s into the paper. Determine the force this proton would feel.
d) Assume that a single electron was placed at point P and given a velocity of 2x10^6 m/s to the right. Determine the force this proton would feel.
