WebFeb 20, 2024 · Figure 11.3. 3: A part of the electromagnetic wave sent out from the antenna at one instant in time. The electric and magnetic fields ( E and B) are in phase, and they are perpendicular to one another and the direction of propagation. For clarity, the waves are shown only along one direction, but they propagate out in other directions too. WebHow can electromagnetic waves be produced? Electromagnetic waves can be produced by vibrating, electrically charged particles. When the particles vibrate the electric field around it vibrates, too. The vibration of the electric field creates a vibrating magnetic field. The vibrations of the two fields together produce EM waves.
