Electromagnetic waves can cause electricity to flow in a conductor, but they do not carry electricity themselves. When an electromagnetic wave interacts with a conductor, an oscillating electric field is created, which can cause the electrons in the conductor to move back and forth. This movement of electrons causes an electric current to flow. This phenomenon underpins the use of electromagnetic waves for wireless communication and power transfer. Radio waves, microwaves, and other types of electromagnetic waves, for example, can be used to carry signals for wireless communication and to transfer power over short distances. It is important to note that electromagnetic waves are not made up of electric charge carriers and thus do not carry electric charge in the same way that a conventional electric current in a wire does.
