What are electromagnetic fields?

Electromagnetic fields are like invisible energy blankets that surround things like your phone or a toaster.

Imagine you have a toy train running on tracks. When it moves, it makes the track vibrate, and if you were really tiny, you might feel those vibrations all around you. That’s kind of what happens with electricity and magnetism: they’re like two sides of the same toy train, working together to make things go.

When you plug in a hair dryer, it uses electricity, which is like the train moving along the track. But that movement also creates a magnetic field, like the vibrations from the train’s motion. Together, they form an electromagnetic field.

You might not see them, but you can feel their work when your phone rings or your microwave heats up, those are all thanks to these invisible energy blankets doing their job!
