Question 15 of 276

Wires 1 and 2 carrying currents $i_1$ and $i_2$ respectively are inclined at an angle $\theta$ to each other. What is the force on a small element dl of wire 2 at a distance of $\mathrm{r}$ from wire 1 (as shown in the figure) due to the magnetic field of wire 1 ?

Show answer and solution

Answer: (C) $\frac{\mu_0}{2 \pi \mathrm{r}} \mathrm{i}_1 \mathrm{i}_2 \mathrm{dl} \cos \theta$
