Electromagnetism is a phenomenon that works behind almost all forces on Earth. Perhaps the only exception is gravity. Its influence is such that experts believe modern life is run through the electromagnetic phenomenon. Let’s try to understand what this means.
Take the case of an electric fan. Its motor works on the principle of electromagnetic induction, which keeps it rotating on and on. This in turn, makes the blade hub of the fan to rotate, blowing air. Another example is that of a loud speaker. It is the electromagnetic force that is responsible for the movement of the coil inside. This in turn, results in the production of sound that can be heard over a long distance.
In the same way, almost all appliances that we use in our daily life, including motors, gadgets, TV, radio, computers, work on the principle of electromagnetism.
In short, all forces involving interaction between atoms can be explained in terms of electromagnetism that occurs between the electrically charged atomic nuclei, and electrons of the atoms.
