Superconductivity

INTRODUCTION
We've all heard about superconductivity. But, do we all know what it
is? How it works and what are its uses? To start talking about
superconductivity, we must try to understand the how 'normal' conductivity
works. This will make it much easier to understand how the 'super' part
functions. In the following paragraphs, I will explain how superconductivity
works, some of the current problems and some examples of its uses.
CONDUCTIVITY
Conductivity is the ability of a substance to carry electricity. Some
substances like copper, aluminium, silver and gold do it very well. They are…
