How do the parts work on an electromagnet...
With this electromagnet you can turn on the swith because there's a process were the electricity flows from the battery to the switch the through big black wires that go around the rivet and send a signel witch makes the magnets work through the end of the rivet then goes back and repeats over and over.
Alex, you need to describe how an electromagnet works, not just how to build one. Building something does mean you understand it completely.
