Electromagnetism is one of the four fundamental interactions of natures. The other three are the strong interaction, the weak Interaction and gravitation. Electromagnetism is the force that causes the interaction between electrically charged particles; the Areas in which this happens are called electromagnetic fields. Electromagnetism practically all the Phenomena in daily life, with the exception of Gravity. Ordinary matter takes its form as a result of Intermolecular forces between individual molecules in matter.
Electromagnetism is also the force which holds electrons and Protons together inside atoms, which are the building blocks of Molecules. This governs the processes involved in chemistry which arise from interactions between the electrons orbiting atoms Electromagnetism manifests as both electric fields and magnetic Fields. Both fields are simply different aspects of Electromagnetism and hence are intrinsically related. Thus، a Changing electric field generates a magnetic field; conversely a Changing magnetic field generates an electric field. This effect is called electromagnetic induction and basis of operation for electrical generators induction motors and transformers. Mathematically speaking magnetic fields and electric fields are Convertible with relative motion as a four vector Electric fields are the cause of several common phenomena Such as electric potential (such as the voltage of a battery) Electric current (such as the flow of electricity through a Flashlight). Magnetic fields are the cause of the force associated with magnets. In quantum electrodynamics electromagnetic
