Also called magnet magnet magnet, is the presence of a magnetic field around the material and their own objects, there are two types of natural and man-made. Artificial magnets usually made of a metal alloy, having a ferromagnetic. Ferromagnetic, refers to a state of a magnetic material, having a spontaneous magnetization phenomenon. Some substances under the action of an external magnetic field in the material after the magnetization of the magnet red, even if the external magnetic field disappears magnet drilling, still able to maintain its state of magnetization of a magnet having a magnetic pen, which is the spontaneous magnetization. All the permanent magnets have a magnet or magnets of the sub. Magnet is an alloy of steel or some artificial artificial magnets made of magnetized, if stored properly, can maintain long-term magnetic. To remind you not to weaken the magnetic magnets, we should note the following: Do not put a magnet strong currents surrounding; magnet can not fire roasted, high temperature; the magnet is not subject to excessive vibration and percussion; Small magnets can not be put together with the large magnet; horseshoe magnet poles should also be applied in making a piece of soft iron poles connected together and to the north and south magnetic poles adjacent inverted. Auxiliary braking system is one of the important parts of oil rigs. When drilling the drill string or casing decentralization, with the driller to operate the main brake to adjust the speed of the drill decentralization, meet the requirements of drilling technology. Permanent magnet eddy current brake if the low-speed brake problem solved, the next promotion and widespread applications in deep drilling rig will be. On large lifting device (such as cranes) motor rotating mechanism plus a permanent magnetic field, eddy current induced magnetic moment to limit the rotation of the motor can reach the speed limit, uniform purpose. The rides, the magnetic field generated by the permanent magnet NdFeB rare earth magnet interference signal strong magnet system can not be considered. If the permanent eddy current brake applied to the recreational facilities will achieve good results. In addition, the permanent eddy current brake Bahn and prospects for this type of linear motor linear actuating device is also very optimistic.
