Looking logically there are electron waves everywhere But if we reduce the size of the particle till its size becomes lesser than the electron waves then it is roughly said confinement Such small particles have remarkably different magnetic properties just because due to small size the fraction of molecules or atoms at the surface is very large and such condition makes changes to properties superparamagnetism ferrimagnetism etc in a material is an example of confinement    See Answer
