What is Electromagnetic Field ?
As we all know, a field is nothing but a physical quantity that’s assigned to every point in space. The electromagnetic field is a combination of electrical and magnetic phenomena that exist in space and it is also created by the motion of charges (electric field) which creates a magnetic field. In simple terminology electromagnetic field is a wave that transports electromagnetic energy with the speed of light. It is a scalar quantity that has only a magnitude not direction associated with it. It is a field described by classical thermodynamics. Maxwell’s law and Lorentz’s force law describe how electric charges constitute current and interact with a magnetic field. Here the important point to catch is without electromagnetic waves we can’t generate electromagnetic fields so both these terms are dependent on each other.
