The magnetic field at the origin due to a current element i\overrightarrow{dl} placed at a point with vectorposition r^{\to} is

Correct Answer is : µ0i4π→dl×→rr3

{\\mu_{0} i}/{4 \\pi} \overrightarrow{{r} \\times{{d}l}^{\to} }/{r^{2}}

{\\mu_{0} i}/{4 \\pi} { {{d}l}^{\to} \times\overrightarrow{r}}/{r^{3}}

{\\mu_{0} i}/{4 \\pi} \overrightarrow{{r} \\times{{d}l}^{\to} }/{r^{3}}

{\\mu_{0} i}/{4 \\pi} { {{d}l}^{\to} \times\overrightarrow{r}}/{r^{2}}
