BCS theory (J. Bardeen, L.N. Cooper, J.R. Schrieffer; 1957)
A theory put forth to describe superconductivity and superfluidity both. This recommend that in the superconducting (or superfluid) state electrons form Cooper pairs, where two electrons behave as a single unit. This takes a nonzero amount of energy to break such kind of pairs, and the imperfections in the superconducting solid (which would lead to resistance normally) are incapable of breaking the pairs, thus no dissipation takes place and there is no resistance.
FACTORS AFFECTING INDUCED EMF By experiment, the following factors may be noted: • The faster the magnet (or coil) is moved, the greater is the deflection obtained on the meter
Magnetism - Basic concepts: 1. Pole strength: The ability of a pole of a magnet to attract or repel another magnetic pole is called its pole strength. Units : A-m 2.
Semi conductors: Semi conductors are these substances which lie among conductor and insulators. Semi conductor is those substances which hardly pass electric current by them
There are imaginary lines or path of the field in the given direction. The lines of force are assumed to make a closed path beginning from N pole and ending at S pole with no loss.
I really just need an interview with someone (it''s a total of nine questions). I have had trouble getting responses and I''m getting desperate about making my deadline. I will als
MOTION: A body is said to be in motion if it alters its position with respect to its surroundings.
