Write any two points of similarities and differences between Coulomb's law for electrostatic force and biodiversity of a magnetic field
a) Both follow inverse-square law, Coulomb's law involves electric charges while magnetic field involves magnetic poles
b) Both involve force interactions, Coulomb's law applies to stationary charges while magnetic field applies to moving charges
c) Both are non-contact forces, Coulomb's law deals with attraction and repulsion of charges while magnetic field deals with alignment of poles
d) Both obey Newton's third law, Coulomb's law applies to conductors while magnetic field applies to ferromagnetic materials
