The guy's claiming that induced B in 'electrical steel' climbs to 500% of applied H.
He's basically claiming runaway self-induction, apparently as an inherent property of this material. So what to make of it? Applying an H field induces a B field, giving their combined field density M, or net magnetisation. If the H field is active as from a coil or solenoid, Lenz's law applies and any change in induced B applies back-EMF to the coil, thus loading its power supply. If the H field is passive however as from a permanent magnet, then the change in induced B is thermodynamically 'free' - work is being done in reducing the system entropy aligning domains, by absorbing phonons within the material - one half of the magnetocaloric effect - and obvs, either way (active or passive) at absolute zero no change in B is possible, so it looks like we're not necessarily in controversial territory invoking ambient heat as a potential source in a case of anomalous self-induction; we could even invoke Sv in an example: place a small neo onto a piece of rough iron with appreciable Sv, maybe amp it up to listen in on the Barkhausen jumps as induced B starts to rise; point is, induced B is rising AFTER all input motion has ceased, hence where's the energy coming from to align the domains against their mutual repulsion? Because a magnetised material is in a stressed state.. a higher energy state. Yet if that energy isn't coming from Mr Hand, then it's obvs environmental. 2LoT be damned. In certain circumstances, anyway. So the only remaining question is: how could B rise significantly higher than applied H? The question no longer where the energy's coming from, so much as the magnetising field? IE. even if we allow it free energy, how can the induced field be 5x denser than the applied field? What property might 'electrical steel' have that could facilitate a runaway self-magnetisation?
