Question

Two long, straight wires carry equal currents in opposite directions as shown in figure. The separation between the wires is 5.0 cm. The magnitude of the magnetic field at a point P midway between the wires is ____ \(\mu T\)

(Given : \(\mu_o = 4\pi \times 10^{-7}\, TmA^{-1}\))

Answer 1

\(= 16 \times 10^{-5} = 160 \mu T\)
