Potential energy in Gauss' gun

[QUOTE="daisy3110, post: 5686789, member: 613314"] There's not that much I can find about it online but [URL]https://www.wired.com/2011/12/does-a-magnet-gun-conserve-momentum[/URL] is quite useful. Yes, I do mean coil gun but using short bar magnets rather than coils. I think what I meant by the orientation was that the definition of magnetic potential energy from the equation U=-mB relates to the alignment of a dipole in the presence of a magnetic field and the energy required to rotate it - [URL]https://en.wikipedia.org/wiki/Magnetic_energy[/URL] [URL]http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/magpot.html[/URL] . - yes I think that is what I mean I think what I want is an equation that would give the potential energy a ball bearing would have as a result of being in the magnetic field in the same was as E = -GmM/r does for gravity. Hope this makes some sort of sense! I'm only in year 12 in the UK so my knowledge of this area is really quite limited. [/QUOTE]
