1.	(a)Write the differences between type I andtype II superconductors.2
Answer» <p>Soft Superconductors (Type I) :</p><p>1. Soft superconductors are those which can tolerate impurities without affecting the superconducting properties.</p><p>2. They have low critical field.</p><p>3. Show complete Meissner effect.</p><p>4. The current flows through the surface only.</p><p>5. Eg. Tin, Aluminium.</p><p>Hard Superconductors (Type II) :</p><p>1. Hard superconductors are those which cannot tolerate impurities, i.e., the impurity affects the superconducting property.</p><p>2. They have high critical field.</p><p>3. Hard super conductors trap magnetic flux and hence Meissner effect is not complete.</p><p>4. It is found that current flows throughout the material.</p><p>5. Eg. Tantalum, Neobium.</p>
