An electromagnetic field contains of both an electric field (which exerts a force on any charge) and a magnetic field (which exerts a force only on moving charges).
Electric and magnetic fields are vector properties (having magnitude and direction of every point in space), but have no mass. They do have energy density that is proportional to the square of each field.
Electromagnetic radiation is a propagating oscillating combination of magnetic and electric fields that oscillate together
The electromagnetic field is composed of two interrelated components: the electric field and the magnetic field. These fields exist due to the presence of electric charges and their motion.
1. Electric Field: The electric field is generated by electric charges. Any charged particle, whether positive or negative, creates an electric field in the space around it. This electric field exerts a force on other electric charges, either attracting or repelling them. The electric field is represented by electric field lines that indicate the direction and strength of the field.
2. Magnetic Field: The magnetic field arises from the motion of electric charges. Whenever an electric charge moves or flows, it generates a magnetic field around it. Similarly to the electric field, the magnetic field exerts a force on moving charges, influencing their motion. The magnetic field is represented by magnetic field lines that illustrate the direction and intensity of the field.
These electric and magnetic fields are interconnected and propagate together as an electromagnetic wave. Through this wave, energy is conveyed and electromagnetic radiation is emitted, such as light, radio waves, and X-rays.
To understand in more detail the components of an electromagnetic field and how they interact, you can study Maxwell's equations, which describe the fundamental principles behind electromagnetism.
