Two long straight current-carrying wires are lined up parallel to one another in vacuum at a distance d. Currents of I1 and I2 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 µo = 1. Please use for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For R use 1/(A*B). For Greek letters such as å or t use lambda and pi.
