Water molecules are polar in nature.


Water molecules are basically, #H_2O# molecules, which have bent shapes. Also, #O# atom is electronegative than #H# atom. So, the entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom.
Thus a polarity develops in each #O-H# bonds, and thus, the water molecules are polar in nature and act like "little magnets".
