Electricity And Magnetism Essay

Electromagnetism and Modern Technologies
The invention of electricity has benefited mankind in several aspects of life ever since the 1800s. Over the course of the past two centuries, scientists have been developing theories that serve as the backbone for various devices today. Such intellectuals have been attempting to understand the credibility and applicability of the already existent theories, such as electricity and magnetism. In addition, they have introduced new concepts by either creating them from scratch, or combining other theories. Electricity, for instance, is a form of energy fueled by the movement of charged particles, called electrons. It is an electrical current if these electrons flow from high to low voltage. If the charged …show more content…
However, the conjunction of significant concepts of electricity and magnetism gave birth to the notion of electromagnetism, allowing modern technologies in the …show more content…
Headphones would not have been invented had it not been for the revolutionary combination of beneficial concepts in both electricity and magnetism. Not that much of a scientific fiction anymore, hovering vehicles seem achievable through magnetic levitation using Lenz’s law, as demonstrated by the already existing maglev trains in Japan, South Korea, and China. It is true that power supply is problematic and expensive. However, it is a decent beginning that shows the possibility of having such modes of transportation. Perhaps, in the future, electricity could be less expensive and more efficient by developing new methods of production, such as the use of nuclear energy to generate electricity. Indeed, electromagnetism proves that electricity and magnets are not merely for having lights and air conditioning, or even sticking notes to the refrigerator. Electromagnetism is an essential concept behind most of today’s modern
