The modern world is powered by electromagnetic energy.
Advanced electromagnetic technology would make it impossible to use cell phones, computers, Bluetooth, GPS, satellite imagery, or scientific understanding of the planet and its surroundings as we know them.
As technology advances, electromagnetic technology becomes more important than ever.

What is Electromagnetic Energy?
The radiant energy of electromagnetic energy is radiant energy traveling at the speed of light in waves.
You can also call it radiant energy, electromagnetic radiation or light.
The transfer of heat can be achieved by electromagnetic radiation. The transfer of heat or energy by electromagnetic waves is possible through a vacuum or medium. This is electromagnetic energy.
James Clerk Maxwell was a 19th-century physicist who discovered electromagnetic radiation. His findings had a significant impact on what would be known as quantum mechanics.
It is similar to an ocean wave in that electromagnetic energy or radiation works as a wave. The radiation is water in this metaphor. The ocean waves that carry water to the shore are called electromagnetic waves.
This energy can be best illustrated by the power required to transport all that water over long distances. The actual electromagnetic energy generation and transfer process are a bit more complicated.
How Do Electromagnetic Waves Work?
The process of creating electromagnetic energy by changing the magnetic and electric fields, which transfer electromagnetic energy. Positive charges can create electric fields or an area of charged space around it that radiates outside. The electric field can be altered by manipulating the charged particle, such as moving it up or down.
Magnetic currents can also create magnetic fields. When the magnetic current oscillates, it can cause magnetic field changes. Electric fields and magnetic fields can influence each other. As one area moves and fluctuates, the other will follow suit. Magnetic fields travel horizontally, while electric fields travel vertically. This allows for polarized alignments of electromagnetic fields.
The essential components of electromagnetic waves are electric and magnetic propagation. A changing magnetic field can create a changing electrical field which can then cause a shifting magnetic field. This creates a chain reaction where the fields oscillate perpendicularly and produce transverse electromagnetic waves.
Waves travel in radiation particles called photons that are carriers. These particles have no mass and travel at the speed of light.
Transverse waves move waves of electromagnetic energy. Momentous photons and magnetic fields power them.
The electromagnetic spectrum is the collection of frequencies and wavelengths electromagnetic waves could have.
What Is the Electromagnetic Spectrum?
The electromagnetic spectrum spans the range of frequencies and wavelengths of electromagnetic radiation. Each type of wave and frequency combination creates different forms of energy.
Electromagnetic frequency is equivalent to the number of wave crests that reach a specific point each second. Frequency can also be thought of as each wave’s peak as it rolls and moves. This frequency measurement, one wave cycle per second, is called a Hertz (Hz).
The speed of a wave is wavelength times frequency. As frequency increases, wavelength decreases, and the more powerful the electromagnetic wave becomes.
