## Main Question or Discussion Point

So if we can one large not moving magnet and a small magnet that is attracted to the large magnet we know that ( http://en.wikipedia.org/wiki/Magnet ) F = μ qm1 qm2 /(4 pi r^2). Here the small magnet is traveling in a straight line because it is attracted by the large magnet.

Where F is force (SI unit: newton) qm1 and qm2 are the magnitudes of magnetic poles (SI unit: ampere-meter) μis the permeability of the intervening medium (SI unit: tesla meter per ampere, henry per meter or newton per ampere squared) r is the separation (SI unit: meter).

To calculate the velocity equation can we equate mass * acceleration = F = μ qm1 qm2 /(4 pi r^2) and integrate for acceleration? this yields Velocity = constant/ r. I was wondering if this is correct. Thank you.
