Magnetic vector equation

WebJul 12, 2024 · In classical electromagnetism, magnetic vector potential (often called A) is the vector quantity defined so that its curl is equal to the magnetic field: ∇ × A = B. Together with the electric potential φ, the magnetic vector potential can be used to specify the electric field E as well. Therefore, many equations of electromagnetism can be ... WebMar 5, 2024 · A = ˆzμI 2π ⋅ ln(2l ρ) = ˆzμI 2π(ln2l − lnρ). Thus we see that the magnetic vector potential in the vicinity of a straight wire is a vector field parallel to the wire. If the wire is of infinite length, the magnetic vector potential is infinite.
