1.	How can it be tested experimentally whether a given liquid is paramagnetic or diamagnetic?
Answer» When a paramagnetic material is kept in a magnetic field it tends to stronger field but when a diamagnetic material is subjected to such a field it tends to move from the stronger to the weaker field. For experimental test the given liquid (for test) is taken a watch glass. The watch glass (with the small quantity of liquid kept in it) is put on the two pole pieces of a strong electromagnetic which are very close to each other. When a current is passed in the electromagnet circuit, either the liquid (in the watch glass) shows an elevation in the middle or shows a depression in the middle. In the former case the liquids under test is a paramagnetic liquid while in the latter case it is a diamagnetic liquid.
