Question: what is the difference between type 1 and type 2 superconductors?
Answer: The difference between type I and type II superconductors can be found in their magnetic behaviour. A type I superconductor keeps out the whole magnetic field until a critical app- lied field Hc reached. ... A type II superconductor will only keep the whole magnetic field out until a first critical field Hc1 is reached.
