>you're only calculating magnetic flux density
Yeah that's what I thought. The entire equation F = H*L doesn't make a lick of sense to me, because it's suggesting that the mmf is only a function of flux density and solenoid length, it doesn't discriminate between a 1mm rod or a 1m rod.

But this image suggests that's the correct way of calculating it even for a toroid.

They do actually enter shoot-through states when transitioning states, just the current that flows isn't that significant.
