In this session we are going to deal on the electro magnetic force which is the attractive force between the charged particles,which shows or contains the electric fields,magnetic fields and light as a part if it. it is also a part of the four fundamental interaction in the universe and the other three of them are 1.strong interaction,2.weak interaction and 3.gravitation. we already discussed about the gravitation in the previous topics and we can have the discussion of the other two interactions in the further posts.
coming to the point the electromagnetic force is the force of attraction and in it we may have the sub topics like electromagnetic waves ,field.and in the electromagnetic waves all the waves which we are studying in the physics are related to the EM-waves in any aspects.examples like light,sound,x-rays,gamma-rays,beta,alpha all every thing comes under this EM-waves.
we already said that an EM-wave consist of the electric and magnetic fields.These two fields align perpendicular to each other.we can separate the two forces into the individual forces by using some techniques which leads to the study of a new chapter called polarization. 

        The study of these forces means the sub parts related to the EM waves and its divisions and laws in it can be simply represented as..
