As is usually shown in elementary courses in electricity and magnetism, the magnetic circulation for an infinite straight current carrying wire is independent of the path encircling the wire. This result is then stated to apply to a wire of any shape, a statement generally offered without proof ...
FROM THE BIOT-SAVART LAW TO AMPRE'S MAGNETIC CIRCUITAL LAW VIA SDG It is well known in classical electrodynamics that the magnetic field given by a current loop and the electric field caused by the corresponding electric d... H Nishimura - 《Far East Journal of Mathematical Sciences》 被引...
