State Ampere’s circuital law.
State Ampere's circuital law, expressing it in the integral form.
उत्तर १
Ampere’s circuital law states that the line integral of magnetic field induction `vecB` around a closed path in vacuum is equal to μ0 times the total current I passing through the surface, i.e. `ointvecB.vec(dl)=mu_0I`
उत्तर २
Ampere’s Circuital Law states that the circulation of the resultant magnetic field along a closed, plane curve is equal to μo times the total current crossing the area bounded by the closed curve, provided the electric field inside the loop remains constant.
In the above illustration, the Ampere’s Circuital Law can be written as follows:
`ointvecB.vec(dl)=mu_0i`
where, i=|i1−i2|
