Why should an alternating current generator be used to generate electromagnetic waves?
The answer is: The AC generator is given a changing electric field, which in turn generates a changing magnetic field, while the DC generator generates a changing electric field the moment it is switched on or off only.
An alternating current generator must be used to generate electromagnetic waves, because it works to give a changing electric field.
An alternating current generator contains wires that rotate around a magnetic pole, and this circular motion results in the production of a changing electric current that allows the generation of electromagnetic waves.
While if a continuous generator is used, it cannot generate electromagnetic waves, but can only generate constant electric current.
Over the years, man has used electromagnetic waves in radio technology, television, radar, mobile phone and others, thanks to the invention of the alternating current generator which is the basis for the generation of induction current.
Therefore, we must take advantage of the use of modern electric generators that provide us with various forms of electromagnetic waves that can be used in a wide range of technological applications.
