Testing My Superconductor - Physics Forums The superconductor is a mixture of organic compounds and that is all i can say so far as you understand Anyway I checked a voltage across superconductor and it is the same as resistance close to 0, I think I will need a lab to confirm the rest, if any of you can suggest any lab or person capable to do so in close proximity so I can send the
Ideal conductor vs superconductor - Physics Forums The most "obvious" difference between a superconductor and an ideal conductor is that the former expels all magnetic fields when it goes through the superconducting transition A perfect conductor would just "freeze" the field, but in an ideal superconductor (well, in a type I at least) the field is always zero
Superconductivity: difference between s-wave and d-wave - Physics Forums However, if make Josephson junctions or SQUIDs out of a d-wave superconductor and orient the electrodes in such as way that you have transport from e g a node to a lobe or from a +lobe to a -lobe (known as a pi-junction since this gives an intrinsic pi-shift of the phase) the effects become much more prominent
Does Impedance Exist in Superconductors Below Their Critical Temperature? For the second kind superconductor, as called high temperature superconductor, the magnetic flux can be enter into the superconducting bulk, and it will be pined at the center of defect Around the flux, one can image a superconducting circuit current is flowing
Why some metals are not superconductors? - Physics Forums 1 Conventional superconductor: 96% hole superconductors (Chapnik rule) 2 HTSC: hole doped Tc much greater than electron doped Tc 3 Phase diagram of Tc and % of doping: concave, superconductor in a limited region of doping 4 Homes scaling law: Tc ~ const*(number of superconducting electrons)*(resistivity in normal state)
Current in a Superconducting Loop - Physics Forums It is not possible to induce a current loop in a superconductor (except in type II where loops can be forced in) In persistent mode magnets, a short section of conductor is made normal and a voltage is applied, current is pumped in, and then the conductor is made superconducting again See Meissner Effect in
Can You Create Your Own Superconductor at Home with Basic Chemistry . . . Here's a few problems : 1 Even the reasonably high Tc superconductors (HTSCs) need close to liquid nitrogen (LN2)temperatures to be superconducting - so need need to buy LN2 everytime you want to do a demo or "use" your HTSC
Current in a superconducting circuit - Physics Forums makes sense so tell me if I've got this right, or if I'm dreadfully wrong: since the resistance of copper is 16 78 nΩ·m at room temperature, I can take an ordinary 9V battery to obtain a current of 536 million amps, run the copper wire to a superconducting circuit, and keep that current of 536 million amps? it sounds kinda ridiculous
How is current induced in superconductors? - Physics Forums The short circuit problem is a different circuit It does not behave the same In the short circuit there is no resistance and no inductance In the superconductor there is no resistance but a very large inductance That makes a huge difference in the circuit behavior Again, resistance is not the only way to get a voltage
Liquid Superconductors: Experiments and Possibilities - Physics Forums The highest temperature superconductor to date is mercury thallium barium calcium copper oxide (Hg12Tl3Ba30Ca30Cu45O125) superconducts at 135 deg kelvin (liquid nitrogen is 77 deg kelvin) The Meissner effect fails with Abrikosov vortices forming aroung non-superconducting channels in the material
