## Main Question or Discussion Point

I could not find a direct formula calculating the retarding force generated from the eddy currents, when a conductor passes a magnetic field at ##v## (##m/s##). Can someone please help me in figuring that out?

I couldn't find a direct way to derive anything either...

There we're some interesting formula's I found online, like ##F = \nu vB^2 \sigma##

##\nu##: Volume of the conductor.

##v##: Velocity of the conductor.

##B##: Magnetic field.

##\sigma##: Conductor's conductivity(I assume electrical, in Ohm.m?).

Is this a valid formula? Or are there any others that are much more accurate?
