Basics of Physics: By Santosh Singh - Now we discuss about "Coulomb's Inverse square law of Magnetism". It is very important law, which define magnitude of Force between two magnetic pole when
force between two identical short bar magnets whose centers are r metres apart is 4.8 Newton when their axis are in the same line if the seperation is increased to 2r metre
