For a wire
Its differential version allows for one to create models of pi ring currents induced in para- and diatropic planar molecules by a perpendicular magnetic field. Likewise, it can be used in tandem with current density to calculate the magnetic shielding tensor. For a wire (*) of infinite length, it states that the flux density is exactly equal to the permeability of free space times the current divided by the quantity two pi times the distance of the point in question from the conductor. Stating that the magnetic induction near a straight conductor is inversely proportional to the distance from the conductor directly proportional to the current in the conductor, FTP, what is this law named for its two French discoverers?
