Two straight parallel wires, running north/south are separated by 12 cm and carry currents of 4 A in the same direction (north). Find the magnitude and direction of the magnetic field at a point midway between the wires. Now find the magnetic field 6 cm east of the "easternmost" wire. Also, calculate the force of one wire on the other. Is it attractive or repulsive?
