"Magnetic electricity"? Magnetism and electricity are the same thing - it's not for nothing it's called electromagnetic force. The ability to convert freely from one to the other was the foundation of most of 20th century technology.

"We're not going to be seeing a magnetic light bulb or anything like that,"

I have a magnetic flashlight, maybe I should send it to them with a note saying, "See what I discovered".
