Explanation / Answer

Here ,

I = 6.5 mA

d1 = 31 cm

d2 = 15 cm

part A) at the magnitude of magnetic field is B

magnitude of magnetic field at A = magnetic field due to wire 1 - magnetic field due to wire 2

magnitude of magnetic field at A = 4pi *10^-7 * (0.065/(2pi * 0.15) - 0.0065/(2pi * 0.31))

magnitude of magnetic field at A = 8.25 *10^-8 T

----------------------------------------------------
part B)
at the point B

magnitude of magnetic field at B = magnetic field due to wire 1 - magnetic field due to wire 2

magnitude of magnetic field at B = 4pi *10^-7 * (0.065/(2pi * 31) - 0.0065/(2pi * 0.31))

magnitude of magnetic field at B = 0 T

part C)

at the point C

magnitude of magnetic field at C = magnetic field due to wire 1 - magnetic field due to wire 2

magnitude of magnetic field at C = 4pi *10^-7 * (0.065/(2pi * 0.15) + 0.0065/(2pi * 0.31))

magnitude of magnetic field at C = 9.09 *10^-8 T
