The magnetic field midway between the two wires is equal to the vector sum of the magnetic fields generated by each wire. The strength of the magnetic fields generated by each wire can be determined using B = μ0*I/2πr, where B is the magnetic field intensity, μ0 is the permeability of free space, I is the current and r is the radius of the wire. Using this formula for each wire, we can find that the magnetic field midway between the two wires is equal to 4.23*10^-7 T.
