Answer:
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.
Advantages of Electromagnetism
•The primary advantage of using an electromagnet over a permanent magnet is that you can control its magnetic field.
•You turn on and off the device's magnetic field, and with many electromagnets, you can even control the power of the magnetic field

Answer:
Advantage
- Advantage of using an electromagnet over a permanent magnet is that you can control its magnetic field.
-Advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding.
Disadvantage
-No control over field strength
-Electromagnetic power sources may not be as useful, or can perhaps be dangerous to use, under certain circumstances.
