Numsgil:
Well, I remember something about how a moving charged particle creates a magnetic field, but a stationary one doesn't.  Things like that.

I have my phyiscs book (parents just mailed it to me) so it just means me sitting down for liek 3 hours and reading it.

Zelos:
magnetism and electrical object moving in it? the formula is:
F= QVB
q is the charge
f is force
v is velocity (relative to the object, it can be the magnet that moves and not the particle)
And B is thr strengh of the magnetic field, SI unit is Tesla wich is a very huge unit. I think that earth magnetic field dont reach 1 Tesla. Anyhow but iron isnt electrical (if it isnt ionized) but it can be magnetic, that means the spin of the atoms is in the same direction so they increase each other.
Nums when it comes to physic I know alot, I´ll gladly help, I can almost (if not) all standard formulas in my head.

Numsgil:
Yeah, that all sounded familiar ;)

I'll go read up on it later today.

Zelos:
I looked on wiki and I found on the article the highers value where 60 micro tesla on earth that is

Zelos:
but that is only if the particle goes 90° relative to the field, else we gotta add sin X where X is the relative angel to the field
