. If you can find a source that disputes the fact that it's ‘electromagnetism’ I would like to read it.

The two aren't mutually exclusive. You can have magnetism without electricity and electricity without magnetism. Electromagnetism is one source of electricity.

As I stated before: In fact moving two magnets past each other creates no electricity. It creates magnetic flux. Holding a wire between two magnets creates no electricity.

How do you think electricity is generated?

I'm not sure what you are getting at. I understand the principles. Did your course teach anything about Faraday or inductance?

Magnetic flux, per your example, is measured in volt/seconds BTW...

Hopeless. Yeesh!

I believe the first statement to be true but I think the second is not. DC flowing through a wire will still produce magnetism as a steady field, AC produces a time variant field which can induce a current in another wire contained within the field. That's why there are DC electromagnets that can produce linear force but no such thing as a DC transformer. You need a time variant field to propagate a EM wave through space. Of course if you move the wire carrying DC with respect to a stationary wire, you are back to a time variant field and have just re-invented the alternator.

I'm rethinking the first statement and I wonder if permanent magnets rely on having their atomic structure aligned so as to have all the electrons spinning (more or less) on the same axis. In which case you have an E field which produces an invariant B field. Thoughts?
