Why is electromagnetic energy important?

Answer 1

This is important because it helps forces of electrons move across the conductor. This happened when the magnetic field changes.

Answer 2

Electromagnetic Field Theory is a very very core and essential subject to learn maxwell's equations and its applications so that they may be used directly in the study of Microwave Devices and Circuits, Antenna Systems and Radar.

Without the concepts used in Electromagnetics these subjects cannot be understood and applied. EMFT forms the base for these theories.

Answer 3

Light is the combination of electric field and magnetic field and so it is also known as electromagnetic wave.
Electric field propagates in the perpendicular direction relative to direction of propagation of wave and magnetic filed propagates in the horizontal direction.
Power plants use the concept of electromagnetism to generate electricity. Many instruments make use of this concept too.

Answer 4

Electromagnetic induction plays a very important role in industries in terms of industrial machinery such as machines in vehicles, mobiles, trucks, factories, etc.in order for the global industries to work and supply the needs of consumers in goods and services.

Answer 5

Michael Faraday discovered electromagnetic induction in 1831. It is the production of a voltage across a conductor when it is exposed to a changing magnetic field.

Answer 6

Electromagnetic induction has a great importance as it is useful with a wide variety of applications. Induction is mainly used in power generation and power transmission.
