Two long parallel wires carry currents `i_(1)` and `i_(2)` such that `i_(1) gt i_(2)`. When the currents are in the same direction, the magnetic field at a point midway between the wires is `6xx10^(-6)T`. If the direction of `i_(2)` is reversed, the field becomes `3xx10^(-5)T`. The ratio `(i_(1))/(i_(2))` is

A

`1/2`

B

2
