# Out of the Loop (no pun intended)

• Devious Squir
In summary, the conversation discusses the concept of creating an electrical current using magnetic fields and ferrous metals, specifically mentioning an electric generator. The idea of utilizing Earth's magnetic field, a rotating circuit in orbit, and space elevators as power cables is also mentioned.

Hey, its been over 6 years since i studied physics seriously, was letting my mind wonder today when i hit upon an idea unfortunately i can't remember the exact physics involved.

Basically i remember something about being able to create an electrical current using magnetic fields and ferous metals moving within this field, can't remember the exact requirements or calculations though, could someone please help me?

Thanks one and all,
Squire

*edited some typos >.<*

Just point out, no longer in education, sorry if this would be classed as the homework section though :S

Welcome to PF Devious,

What you describe is an electric generator. http://amasci.com/amateur/coilgen.html" has a video demonstration as well as some elementary theory regarding [AC] generators.

Nope, it isn't classed as homework and you've posted it in the right place

thanks, and now for my idea (its a gradeous one so feel free to laugh and the impossiblity of it) basically, the magnetic field is Earth's, the rotation circuit is a massive ring in orbit of the world, thirdly several of the "space elveators" that NASA are on about these days act as power cables to the surface of the planet, result, massive "free" energy source.
