Answer:
Advantages of Electromagnetism
It can be turned on and off by cutting of the electrical current.
It does minimal harm to the human body because it's not using x-rays like an x-ray does.
It is easy to use and can help is many medical and casual things.
Electromagnetism is the reason why we can toggle on and off things like our house lights for example.
Electromagnetism led to the discovery of the electromagnetic spectrum
Disadvantages of Electromagnetism
Electromagnets heat up very fast
It takes a lot of energy to use
If cranked up to high it could be dangerous
There is radiation that comes from electromagnetism, and those types of radiation are showed in the electromagnetic spectrum
Explanation:

Two advantages of electromagnets over permanent magnets are :
(1) : The magnetic strength of electromagnets can either be increased or decreased but this cannot be done in permanent magnets.
(2) : Magnetic power of electromagnets is more than compared to permanent magnets.
Due to these advantages, electromagnets have more application than permanent magnets.
Disadvantages of Electromagnetism
Electromagnets heat up very fast.
It takes a lot of energy to use.
If cranked up to high it could be dangerous.
There is radiation that comes from electromagnetism, and those types of radiation are showed in the electromagnetic spectrum.
