Hey everyone,
I'm learning about B and H fields in electromagnetic waves and propagation class. Trying to wrap my head around the idea that magnetic fields wrap around current carrying wires.
Consider this:
If you were to take a clear, hollow cylinder, drill a hole at both ends, run a copper wire concentrically down the middle, fill it with baby oil and iron filings and seal both ends.
Then energize the wire with a voltage so that constant current flows...
Describe the movement of the iron filings.
I'm curious - will they actually start moving in circles around the wire?
Cheers and Thanks!
