Two 50m-long wires are are hung parallel to each other, 1m apart. The first wire has a current of 10A flowing through it. The second wire has a current of 20A flowing through it. The currents are in the same direction (a) Find the magnetic field at a point 0.25m from the midpoint of the 10A wire. (b) Find the force each wire exerts on the other.
