A manufacturing method and a manufacturing apparatus for a printing magnetic orientation master and a magnetic pigment presswork are provided. The manufacturing method for a printing magnetic orientation master comprises: providing a magnet; using a heat radiation beam to heat a partial area of the magnet so that a new magnetic domain structure is formed in the partial area through self-magnetization of the magnet to change a magnetic-field distribution in the partial area; and removing the heat radiation beam to keep the new magnetic domain structure after it is decreased to a normal temperature so that the changed magnetic-field distribution is kept in the partial area, thus forming the printing magnetic orientation master having a predetermined magnetic orientation pattern. This can simplify the manufacturing process of the printing magnetic orientation master and allow the printing magnetic orientation master to carry abundant pattern information. |

A magnetiser for a pipeline inspection tool. The magnetiser comprises a ferromagnetic base member, a pair of driving magnets mounted at spatially separate locations on the base member and a flux enhancing magnet mounted on the base member adjacent to one or both of the driving magnets. The directions of magnetisation of the pair of driving magnets extend in opposite senses to each other, towards and away from the base member respectively to create a magnetic circuit that includes a flux path between the driving magnets which passes through the base member. The flux enhancing magnet has a direction of magnetisation substantially aligned with the direction of magnetic flux on the flux path, the flux enhancing magnet being magnetically coupled to the adjacent driving magnets to drive flux around the magnetic circuit and thereby enhance the magnitude of a magnetic field exhibited by the magnetic circuit outside the magnetiser. |

In an electrical energy generator, at least one permanent magnet generates flux and a magnetizable member forms the single flux path. An electrically conductive coil is wound around the magnetizable member, and a plurality of flux switches are operative to sequentially reverse the flux from the magnet through the member, thereby inducing electrical current in the coil. A “Figure-8” construction comprises two continuous loops of magnetizable material sharing a magnetizable member common to both loops. An alternative configuration uses stacked loops and a separate piece of material acting as the magnetizable member. One end of the magnet is coupled to one of the loops, with the other end being coupled to the other loop. Each loop further includes two flux switches operated in a 2×2 sequence to sequentially reverse the flux through the magnetizable member. A relatively small amount of electrical power is used to control the magnetic flux of a permanent magnet by switching the flux between alternate paths. The resulting power from the switched magnetic flux yields substantially more power than the power required for the input switching. |
