Two long straight current-carrying wires are lined up parallel to one another in vacuum at a distance ?d. Currents of ?1I1 and ?2I2 flow through the wires, both in the same direction generating the field of ??BM at a midpoint between them. Write down an expression for ??BM in terms of the currents running in each of the wires. Assume vacuum permeability ?0=1μ0=1. Please use "*" for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For 1?∗?1A∗B use 1/(A*B). For Greek letters such as ?λ or ?π use lambda and pi.
