What is Electromagnetic?

Electromagnetic refers to the interaction between electricity and magnetism. It is a fundamental force of nature that is responsible for the behavior of electrically charged particles and the transmission of energy through electromagnetic waves.

Key Concepts to Understand

• Electricity: The flow of electric charge through a conductor.
• Magnetism: The property of certain materials to attract or repel each other.
• Electromagnetic Waves: Waves of energy that are created by the vibration of electrically charged particles.
• Electromagnetic Spectrum: The range of all possible frequencies of electromagnetic radiation.
• Electromagnetic Induction: The process of generating an electromotive force by moving a conductor through a magnetic field.

Examples of Electromagnetic Phenomena

There are numerous examples of electromagnetic phenomena in everyday life, including:

• Light and other forms of electromagnetic radiation
