Incomplete Network and Where do magnets come from?

One Hundred Thirty Ninth Post: Incomplete Network and Where do magnets come from?

Network settings are made simple today with the standard being TCP/IP, but there are other things such as getting XP Home to see XP Pro. Also the firewall must be configured properly. It just leads to a bunch more settings. This basically means that my network doesn’t work yet.

But another interesting fact I read is about electricity and magnetism. When electricity flows through a wire it has a magnetic force around it. This is probably why electromagnets can be created. So the force is there it is just hidden. If you ever used a remote control car and happened to pass under a power line, you may notice that the car does not respond and may drive itself backwards or off course. This is because of some sort of force of interference from the power line.

The Greeks knew about static electricity. They also new (magnetite) stones would attract iron. I was always puzzled where these magnets came from. How can electricity be created without a magnet? Electric is made when a magnet is rotated inside a coil of wire. So the magnet is the key. Who invented the magnet or at least discovered it?
