Barium ferrite is a topological insulator. Unlike other types of magnets, Barium ferrite does not conduct electricity. It also has a characteristic known as perpendicular magnetic anisotropy (PMA). This situation originates from the inherent magneto-crystalline anisotropy of the insulator and not the interfacial anisotropy in other situations. As a Mott insulator, it possesses strong spin orbit coupling. This characteristic produces a log jam of electrons that stops current from flowing.
See for details, https://phys.org/news/2017-02-reveals-quantum-state-strange-insulating.html Research reveals novel quantum state in strange insulating materialsFebruary 9, 2017 As a Mott insulator, Barium ferrite also has another characteristic called linear magnetoresistance (LMR). The origin of the LMR in this case is likely related to small density variations throughout the solid which cannot be avoided in conventional material growth techniques. This leads to a contribution of a linear Hall resistance caused by the Lorentz force in a magnetic field <https://phys.org/tags/magnetic+field/> on a moving electron on the measured magnetoresistance. Read more at: https://phys.org/news/2016-12-linear-magnetoresistanceexotic-classical.html#jCp The origin of linear magnetoresistance—exotic or classical? IMHO, the differences in the two types of magnetic materials used in the Sweet system and the Manelas system make operating quantum mechanical mechanisms of these two systems different. Finally, a magnetizing coil wrapped around the edge of the magnetic billet will produce a field where the edges of the billet demonstrates a south pole. This is because the field lines nearest the magnetizing coil are the strongest and a north pole bubble in the middle where the magnetic field lines are the weakest. A huge amount of work must be done to understand how these types of *Vacuum Triode Amplifier *systems work. But the prospect of understanding how the reported trust production characteristics work like what occurs in the EDDrive system might make the investment in all that work worthwhile. Finally, unlike LENR, the lack of subatomic particle production is also a selling feature of these systems well worth the work to understand.
