Did they give the value of the magnetic field (emit by the module) ?, how they want to do it (from simple electromagnet version XXXXL or to use a ferromagnetic material also XXXXL) Because with electromagnets, the energy should be enormous (although possible), with a ferromagnetic material, it is possible that this is not realizable (hard to have a strong magnetic field, constraint of transport, ...) The electro-magnet is better, if it uses a nuclear reactor, it can be widely envisaged (the ele…

(Quote from Huor) HO, Does this explain the fact that the eating field is of low power, but of a great distance on earth ??? (Because the field of the earth is 50 micro tesla, but for a very large area, while electro magnets of 10 tesla (1e + 7 micro tesla) are very powerful but do not have a very long range), bizzar ?

(Quote from Huor) An electromagnet is composed of an ENTREFER, and a copper wire winding (a coil), if you feed just one coil, the result will be mediocre, but, with the ENTREFER, which is composed of a ferromagnetic material, Will '' directed '' the magnetic field entrefer (sorry no traduction) = Increase the reluctance of the magnetic circuit so as to be able to increase the value of the intensity which causes saturation of the magnetic circuit. this is a true electromagnet :
