When you apply a magnetic field to a superconductor it increases the energy of the anchored orbitals and this decreases their density. When this decrease in density reaches a critical density, superconduction cannot occur anymore. The same happens when such a material comes into contact with a...
According to me they are deluded. Cooper Pairs are not required for superconduction and probably do not even exist: also not in the form of parallel spins.
Yes it is so since the charge-carriers cancel the applied electric field by becoming polarized. With an AC current the direction of...
The first thing that they do not want to believe is that the charge-carriers are not electron-pairs but are singly-charged. The next thing they do not want to believe is that these charge-carriers are stationary (anchored) when there is no current flowing: i.e. That such a phase must be an...
I am not going to comment on the extracts posted by William Gaatjies in detail since the interpretation of the results of what he has quoted, by the researchers who measured these results, is naive. Yes there are two gaps involved in the ceramic superconductors, and yes when you inject a large...
Well why do you not patent this and make pots full of money? Can you generate a current through space flowing from one contact to another without applying a voltage over the two contacts or first accelerating the charge-carriers by applying a voltage. Please tell me how? It seems to me that you...
Schenley101: The way current flows through superconductors is different than a normal conductor. Instead of electrons independently flowing through a lattice of atoms, pairs of electrons are formed with a gap between them.
Wrong: I can easily prove from calculating the flux quantum correctly...
Bwanaaa: so what's the answer? how fast do electrons drift in a superconductor?
Thousands of times faster than in a normal resistor. The actual speed obviously depends on the material.
How can current be measured in a superconductor? The minute you attach a device to a superconductor to measure...
TuxDave:What about DC drift velocity? Isn't the skin depth = the whole conductor at 0Hz?
Whether a current is driven by an electric-field THROUGH a material or driven by an electric-field on the surface of a material, in both cases there must be acceleration involved: And when acceleration is...
TuxDave: I would expect the drift velocity in a super conductor to be orders of magnitude larger than the drift velocity of a copper wire.
Correct it is far higher than in a resistor; and I can prove mathematically that it must be so. It is not the magnitude that is the same but the paradoxical...
Quote from William Gaatjies: But according to the article, the drift velocity of the electrons is the same as in a normal conductor where resistance occurs.
NO! Not the SAME but also constant: The constant drift velocity within a resistor is caused by multiple acceleration-scattering of the...
