Question

advantage of Electromagnet and four features of domestic electric wiring​

Answer 1

The main advantage of an electromagnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding.

advantage is that when connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet.
