Consider two parallel wires placed a distance of 13.5 cm apart. The current in the first wire is 11.50A and the current in the second wire is 15.25A. 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.

Answer #1

Magnetic field, B = u0 I/2 pi r

B = B1 + B2

B = (4 pi x 10^-7/2 pi x 0.0675)(11.5 + 15.25)

B = 79.26 uT
