Maxwell claimed that time-varying electric fields can generate magnetic fields. The given diagram above demonstrates a linearly polarized electromagnetic wave propagating in the z-direction with oscillating electric field E in the x-direction and oscillating magnetic field B in the y-direction. Time varying electric field + Time varying magnetic field = Electromagnetic waves. Maxwell concluded that these EM waves have so many special properties which can be utilized for many practical purposes. When electric and magnetic fields combine together and vary with time, they both give rise to electromagnetic waves.Įlectromagnetic equations are derived from Maxwell’s equations. These waves are basically coupled time varying electric and magnetic fields which propagate in space.Īs these are waves associated with electricity and magnetism, they definitely would propagate in space. Voice transmission in mobile phones is made possible because of electromagnetic waves.Įlectromagnetic (EM) waves are the waves which are in relation to both electricity and magnetism. remotes, remote cars, LED TV, microwave ovens, etc. They are utilized in electronic appliances like T.V. Radio and television broadcasting signals are transmitted with the help of electromagnetic waves.Įlectromagnetic waves help in determining the speed of passing vehicles. For instance, in laser eye surgery and in x-rays. In the medical field, these waves have very important applications. They also help to evaluate the speed of aero-planes. These waves help in aircraft navigation and help the pilot for smooth take-off and landing of aero-planes. We are able to see everything surrounding us because of electromagnetic waves. Some of the important applications of electromagnetic waves are as follows: One of the most important applications of electromagnetic waves is in the field of communication. Let us discuss electromagnetic waves, their properties and characteristics, and also their practical uses in our everyday life.
