Jean Taisner (or Taisnier) (Latin: Johannes Taisnerius; 1508, Ath, Habsburg Netherlands – 1562, Cologne) was a musician, astrologer, and self-styled mathematician who published a number of works. A publication of his entitled Opusculum perpetua memoria dignissimum, de natura magnetis et ejus effectibus, Item de motu continuo is considered a piece of plagiarism, as Taisner presents, as though his own, the Epistola de magnete of Peter of Maricourt and a treatise on the fall of bodies by Gianbattista Benedetti.
The work describes a magnetic-based perpetual motion machine consisting of a ramp, a magnet stone and an iron ball.
Peter of Maricourt had earlier noted such a system which made use of the strength of the magnet stone.
This runs into trouble because the path integral of force on a closed loop in a magnetic field is zero (see History of perpetual motion machines).
