The net magnetic field between the two parallel wires is determined as 1775 nT.
Magnetic field at wire 2 due to current 1
The magnetic field is calculated as follows;
[tex]B_z_1 = \frac{\mu _0 I_1}{2\pi r} \\\\B_z_1 = \frac{4\pi \times 10^{-7} \times 42 }{2\pi \times 7} \\\\B_z_1 = 1.2 \times 10^{-6} \ T[/tex]
Magnetic field at wire 1 due to current 2
The magnetic field is calculated as follows;
[tex]B_z_2= \frac{\mu _0 I_2}{2\pi r} \\\\B_z_2 = \frac{4\pi \times 10^{-7} \times 23 }{2\pi \times 8} \\\\B_z_2 = 5.75 \times 10^{-7} \ T[/tex]
Net magnetic field
B = BZ1 + BZ2
B = 1.2 x 10⁻⁶ + 5.75 x 10⁻⁷
B = 1.775 x 10⁻⁶ T
B = 1775 x 10⁻⁹ T
B = 1775 T nT
