Solution

Q.
Two long, straight wires carry equal currents in opposite directions as shown in the 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 ______ $μT$ .

$(Given: μ_{0} = 4 π \times 10^{- 7} {TmA}^{- 1})$ [2024]

Ans.
(160)

$B = (\frac{μ_{0} i}{2 π a}) \times 2 = \frac{4 π \times 10^{- 7} \times 10}{π \times (\frac{5}{2} \times 10^{- 2})}$

$= 16 \times 10^{- 5} = 160 μ T$
