When I looked up the electromagnetic wave, it was called an electric field + a magnetic field.
Do you mean the magnetic field of a magnet?
Then magnets are harmful, but I've never heard of them.

The magnetic field of the magnet is correct, but the magnetic field of the magnet is not so powerful that it has a bad effect.
Electricity generates a lot of electric and magnetic fields depending on the amount of supply.
