MHT CET 2022 11th August Evening Shift | Moving Charges and Magnetism Question 68 | Physics

Two parallel conducting wires of equal length are placed distance 'd' apart, carry currents '$$\mathrm{I}_1$$' and '$$\mathrm{I}_2$$' respectively in opposite directions. The resultant magnetic field at the midpoint of the distance between both the wires is

$$\frac{\mu_0\left(I_1-I_2\right)}{\pi \mathrm{d}}$$

$$\frac{\mu_0\left(I_1+I_2\right)}{2 \pi d}$$

$$\frac{\mu_0\left(I_1-I_2\right)}{2 \pi \mathrm{d}}$$

$$\frac{\mu_0\left(I_1+I_2\right)}{\pi d}$$
