  • 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
  • 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
  • Superconductor at room temp - Physics Forums
    You may not be aware that there are no room temperature superconductors—yet Superconductors expel magnetic fields, so one way to tell if you have a superconductor is to place it in a uniform magnetic field, cool it through the transition temperature, and watch the external fields change
  • 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
  • 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
  • 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
  • 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
