Before word with so many definitions. Physics is one

we unlocked the word electromagnetics let’s discuss first where does it came
from, by defining its trunk which is Physics. It is a widespread word with so
many definitions. Physics is one of the most fundamental of the sciences.
Scientists of all disciplines use the ideas of physics. It is also the
foundation of all engineering and technology. No engineer could design a
flat-screen TV, without first understanding the basic laws of physics.
Electromagnetics undergoes in classical physics, it is has
four fundamental forces of nature which determine the interactions between
matter and energy which include strong interaction, weak interaction,
gravitational force and electromagnetic force. Scientists that specialize in
electromagnetism investigate phenomena such as electrically charged particles,
magnetic attraction and electromagnetic fields.

            Since we’re done in physics lets now
define electromagnetics. It
is all around us. In simple terms, every time we turn a power switch on, every
time we press a key on our computer keyboard, or every time we perform a
similar action involving an everyday electrical device, EM comes into play. It
is the foundation for the technologies of electrical and computer engineering,
spanning the entire electromagnetic spectrum, from dc to light, from the
electrically and magnetically based technologies to the electronics
technologies to the photonics technologies. It is a
branch of physics in which electric and magnetic phenomena are studied. An
electromagnetic field is made up of interdependent electric and magnetic
fields, which is the case when the fields are varying with time, that is, they
are dynamic. An electric field is a force field that acts upon material bodies
by virtue of their property of charge, just as a gravitational field is a force
field that acts upon them by virtue of their property of mass. A magnetic field
is a force field that acts upon charges in motion.

            The principal domains of
electromagnetism are the following ones: Electrostatics, Electrokinetics,
Magnetostatics and Electrodynamics. These domains are very useful for the study
of macroscopic phenomena and in practical applications. The first of these to
impress humanity was the electrical phenomenon of lightning, often believed to
be a tool of heaven, and the less powerful magnetic force that caused
lodestones to point north. The explanation and application of these invisible
forces during the eighteenth and nineteenth centuries vaulted electrical
engineering to the forefront of commercial interest as motors, generators,
electric lights, batteries, heaters, telephones, record players, and many other
devices emerged. The second set is to delivered the ability to communicate
instantly without wires around the world, not only dots and dashes, but also
voice, images, and data. Third came electronics and photonics, the ability to
electrically manipulate individual electrons and atoms in vacuum and in matter
so as to generate, amplify, manipulate, and detect electromagnetic signals. The
fourth set of electrical phenomena involves cybernetics and informatics — the
manipulation of electrical signals so complex that entirely new classes of
functionality are obtained, such as optimum signal processing, computers,
robotics, and artificial intelligence.
