Physics Vibes Pk (PV) on Instagram: "Ampere’s Circuital Law Definition: Ampere’s Circuital Law states that the line integral of the magnetic field (𝐵) around any closed path is equal to μ₀ times the total current (I) enclosed by that path. Mathematical Form: \oint B \cdot dl = \mu_0 I_{\text{enclosed}} Where: = Magnetic field = Small element of the closed path = Permeability of free space = Total current enclosed by the path Explanation: Ampere’s law helps us find the magnetic field produced by
