Electromagnetic power sources may not be as useful, or can perhaps be dangerous to use, under certain circumstances. For instance, if you need to have a power source that must have a regulated current output, both AC and DC power generators would need to be run at a non-varying speed
There is radiation that comes from electromagnetism, and those types of radiation are showed in the electromagnetic spectrum. Home.
Advantage of electromagnet
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.
