A law of physics which states that the magnetic flux density (magnetic induction) near a long, straight conductor is directly proportional to the current in the conductor and inversely proportional to the distance from the conductor. There is also a law in fluid dynamics bearing this name; it is concerned with vortex motion, and bears a close analogy to the law discussed in the present article.
