Electromagnetic Fields
Electromagnetic fields are invisible forces created by electrically charged objects. They consist of electric fields, which arise from static charges, and magnetic fields, which emerge from moving charges (like current in a wire). Together, they govern how charged particles interact, influencing everything from lightning to the operation of electrical devices. In electrodynamics and classical electromagnetism, these fields are described by fundamental laws such as Maxwell's equations. In kinetic theory, particularly in plasmas (ionized gases), understanding electromagnetic fields helps explain particle behavior, energy transfer, and how these systems respond to external influences.

Electromagnetic fields are areas of energy created by electric charges and magnets. They consist of electric fields, which arise from charged particles, and magnetic fields, generated by magnets or moving charges. These fields interact with each other and can affect other charges and magnets within their reach. Electromagnetic fields are responsible for many everyday phenomena, such as light, radio waves, and the functioning of electrical devices. They play a crucial role in communication technologies, medical imaging, and even the way the Earth’s magnetic field protects us from solar radiation.

Electromagnetic fields (EM fields) are invisible areas of energy created by electrically charged particles, like electrons. They combine electric fields (caused by static electricity) and magnetic fields (generated by moving charges). EM fields are fundamental to how we experience electricity and magnetism in everyday life, affecting technologies like radios, microwaves, and wireless communication. They propagate through space, carrying energy and information. The strength and behavior of these fields are key to various scientific and practical applications, from powering devices to medical imaging. Understanding EM fields helps us grasp the principles behind much of modern technology.
