CHAPTER 27 SOURCES OF MAGNETIC FIELD • Magnetic field due
... Each element acts like a wire carrying part of the total current. It produces a magnetic field that is concentric, i.e., not down the tube. But, cancellation from all the diametrically opposite elements produces zero net field inside! So, there is no magnetic field inside the tube at all. Note that ...

SUPERCONDUCTIVITY
... In the superconductive state the current carrying species is the electron pair. For the Cooper pair to scatter it would have to change its state (like an electron in normal metal). However, the Cooper pair is coupled to a large number of other Cooper pairs and so the whole collective of Cooper pairs ...
