AI Thread Summary

In superconductors, when a specimen is cooled below the critical temperature (Tc) in the presence of a magnetic field, a screening current is generated. The energy for initiating this current primarily comes from the magnetic field applied before cooling. If the magnetic field is not the source, the energy can be attributed to the cooling process itself. This highlights the interplay between temperature changes and magnetic fields in the behavior of superconductors. Understanding this energy source is crucial for further research in superconductivity.

suppose we have a superconductor speciment above Tc, and we put it in magnetic field. then we cool it down to below Tc, then a screening current is produced.

where does the electron get the energy to initiate the current on the first time?

Magnetic field. If not, then the energy it gets is from the energy you used to cool it down.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
