Consider two parallel wires placed a distance of 12.5 cm apart. The current in the first wire is 4.50A and the current in the second wire is 4.25A. If the currents are in opposite directions, find the magnitude of the combined magnetic field at the midpoint between the two wires. Calculate the answer in micro-tesla (µT) and rounded to three significant figures.

PLEASE show work, I am confused on how to get the answer.

Thank you
