According to Ampere's circuital law, the circulating magnetic field along a closed plane curve of current distribution is equal to:
1
\(\frac{1}{\mu_0}\) times the total current through the surface
2
2μ0 times the total current through the surface
3
\(\frac{1}{2\mu_0}\) times the total current through the surface
4
μ0 times the total current through the surface
