B=μ0I/2πr
B1 = (4π×10^7)(8.0A)/(2π×0.030m)
B2 = (4π×10^7)(-8.0A)/(2π×0.150m)
BA = B1 + B2
B1 = (4π×10^7)(8.0A)/(2π×0.060m)
B2 = (4π×10^7)(-8.0A)/(2π×-0.060m)
BB = B1 + B2
B1 = (4π×10^7)(8.0A)/(2π×0.030m)
B2 = (4π×10^7)(-8.0A)/(2π×0.150m)
BA = B1 + B2
B1 = (4π×10^7)(8.0A)/(2π×0.060m)
B2 = (4π×10^7)(-8.0A)/(2π×-0.060m)
BB = B1 + B2

This math is correct except that u0 = [(4)(pi)]x10^-7, not positive 7. Otherwise, thanks for your work.
