释义 | Ampère's law A law of the form dB = (µoI sinθ dl)/4πr2 , where dB is the infinitesimal element of the magnitude of the magnetic flux density (see magnetic field) at a distance r at a point P from the element length dl of a conductor, µo is the magnetic permeability of free space, I is the current flowing through the conductor, and θ is the angle between the direction of the current and the line joining the element of the conductor and P. It is also called the Ampère-Laplace law after the French mathematician Pierre-Simon de Laplace (1749–1827) |
