Open the Radio Waves and Electromagnetic Fields Simulation to the right by clicking on the image. Your simulation screen should look similar to the one shown. This screen shows a radio station transmitting antenna on the left and a receiving antenna on the right.
As you can see from these activities, electricity and magnetism are directly related. Moving charges create magnetic fields and changing magnetic fields create electric fields. It is this interaction between electricity and magnetism that allows electromagnetic waves to travel without a medium. The changing electric field creates a changing magnetic field, which in turn creates an electric field. The combined oscillating field travels through space.”
