# Ampere and Pythagoras

Two parallel wires carry $$1~\mbox{A}$$ currents in unknown directions. The distance between the axes of the wires is $$10~\mbox{cm}$$. What is the magnitude of the magnetic field $$B$$ in Teslas at a point P located $$6~\mbox{cm}$$ away from the axis of one of the wires and $$8~\mbox{cm}$$ away from the axis of the other wire?

Details and assumptions

$\frac{\mu_{0}}{4\pi}= 10^{-7}~\mbox{H/m}$
