I don't agree. The collapsing field in a coil is a classic chance to get zpe energy (viz Lee & Yang, Nobel Physics Prize, 1957 etc)

hi Paul

i understand what you're saying, and there's at least one paper by Zaev looking at exactly this issue and reporting anomalous excess energy - and a separate paper by other authors presenting results which show similar behaviour from coil-collapse energy in a pulse-motor

in this second case the gain effect was assymetrical depending on whether rotor mag orientation was S-pole facing stator or N-pole

however, i'm just reporting measured results from my tests - and so far (when i use the correct value!) the energy released from the energised coil matches the input energy

but, as dorro questions above, i haven't yet tried to quantify the work which may be obtainable from the magnetic component of the stored field

more to do

all the best
