two long parallel straight wire are seperated by a distance r in vacuum. an electric current flow through each wire in opposite direction, the magnetic flux density at the centre between 2 wires is (2)(ε0)/(πr) ... can someone explain why?

    ok how do you know that the magnetic flux between two wires is (2)(e0)/(pi times r) ?

    \[\large \phi B =B A \cos (\theta)\]

    ϕB=BAcos(θ) is for finding the magnetic flux density
