We prove as Newton's 3rd law holds in static aspects of Electromagnetism it holds also in dynamic aspects of it. Force on current-carrying wire in external magnetic field and force on magnetic needle in Oersted's experiment are action-reaction forces. By considering point magnetic charges, mutual effects of electric and magnetic charges on themselves and on each other are presented in the forms of vectorial relations. Using these relations, incorrectness of a usual manner which eventually leads to the deviation from the classical physics and to the rejection of the Galilean transformations and to the resort to the special relativity is proven. Almost all the fundamental relations in the current electromagnetic theory are rewritten in new forms by using the presented fundamental vectorial relations. The way electromagnetic wave propagates through tiny magnetic and electric dipoles is easily explained by using the mentioned relations and obtaining the new form of Maxwell's equations and deducing the wave equations from them. Fresnel coefficients are obtained in their new forms. In this new approach, reflectance and transmittance are introduced the sum of which is identical with one.
