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 …showed first 75 words of 1628 total…

CONCLUSION As time goes by, transition temperature, critical field (maximum magnetic field intensity that a superconductor can support before failing), current capacity and all other problems are improving slowly. But, at least they show that we are moving in the right direction. A lot of people are getting interested in that field since it promises a lot for the future.
