Anyone able to help?

Thanks for the help! I must have slept through that day in physics... Here's another site I found that was helpful if anyone else is interested: http://micro.magnet.fsu.edu/electromag/electricity/inductance.html

Are there certain formulas relating to this so I can actually calculate how much of an electric field is being produced?

I know that electricity running through a circuit produces a magnetic field...does this work the other way around? Does a permanent magnet in a circuit produce electricity? A colleague of mine is trying to convince me that moving a magnet back and forth in the presence of a circuit can produce...

In regards to superposition, I haven't found a good equation for the force from a magnet at a distance. I've found one for the force from a magnet on steel at a distance. However, the magnets I'm trying to use are not composed of steel.

It's not a homework problem. I reposted it in the general physics forum with some additional info.

How do you calculate the attraction and repulsion forces between two magnets? I know it depends on many factors, so for example: two 0.5"x0.5"x0.25" Neodynium magnets with a grade of 42 (Br = 13200 Gauss) that are 0.25" apart from each other (only air is separating them). Thanks for any help...
