Two very long wires of unknown lengths are a parallel distance of 2 m from each other. If both wires have 3 A of current flowing through them in the same direction, what must the force per unit length on each wire be?
BONUS:Is the mutual force between the wires attractive or repulsive?

Wire 1 lies along the line and carries a current in the positive x direction; wire 2 lies along the y = 0 line and carries a current in the negative x direction. What is the magnitude of the magnetic field at the point (, , )?1541views
