Hey there.
Please understand the band theory is only an analogy that is used to explain the energy requirements to promote conductivity. In other words, electrons do not PHYSICALLY jump into a conduction band upon conduction. It simply proposes the relative amounts of energy needed to promote...
Hey. Thanks for your reply. Yes I completely agree with you.
Although, the other argument is that they ARE eddy currents. As the magnet falls due to gravity above the superconductor, it gives rise to a change in magnetic flux and induces perfect eddy currents in the superconductor. This in...
Ok. So I'm really confused. The variation in perspectives by physics authors has really left me worried.
With the meissner effect, are the currents induced in the surface of the super-conductor eddy currents? If not what type of currents are they? Could you provide a justification, as no text...
