Question

In your own words, discuss two ways that we use electromagnetic waves.

I know that we use the for picking up cars and scrap-metal in junk-yards, but I think they can also be used as a part in a circuit? Like a doorbell. Am i right? If not how else are they used?

Answer 1

electromagnetism is not the same thing as magnetism, or electromagnets. So your magnet answer is incorrect.

Answer 2

Two ways we do use it would be as means of communication, via radio waves, and to illuminate our homes at night, via the visible light spectrum.

Answer 3

Thanks again. :)

Answer 4

Of course :)
