  Dan -

  Bringing force into the picture complicates the picture.  The force would
not be the same because of  F = ma. The power would change and so would the

   Power = force x dL/dt = energy/dt        L = distance
   Note that force x distance = work = energy

  The energy in the powder would be the same in both cases. 

  It is interesting to note that force is a factor in Tesla coils. The large
instantaneous  currents in the primary circuit can cause large forces
between the primary conductors and between the primary coil windings.
