are simple devices that mimic the behaviour of natural
magnets
2. As the electrical current moves around the
of the coil, it generates a
magnetic field like that of a small bar magnet.
3.. Changing the
for a different metal will make the electromagnet
stronger or weaker.
4. Although metal
are very efficient conductors of electricity, they still
have some resistance to the flow of current..
5. Changing the amount of flowing through the electromagnet will also
change the field it produces​
