Electromagnetic Field

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields, and it is responsible for electromagnetic radiation such as light. It is one of the four fundamental interactions (commonly called forces) in nature, together with the strong interaction, the weak interaction, and gravitation.

Dynamics mechanical engineering is the branch of mechanics that deals with the study of objects in motion and the forces causing such motion. Dynamics can be further classified into two types: kinematics and kinetics. Kinematics is the study of the motion of bodies without consideration of the cause of the motion. Kinematics deals with the space-time relationship of the motion of a body. Some examples of kinematic concepts are displacement, velocity and acceleration.

 While Kinetics is the branch of mechanics which deals with the study of the motion of bodies by considering the cause of motion.
