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