Please,if you have the circuit still, could you measure flyback energy when coil in your circuit is exactly inline with Earth magnetic field in N-S direction and then in E-W direction ?

hi Forest

i'll try to check your requested setup when i'm working with this circuit - however, i should point out that my calcs which showed greater energy returned from the coil than stored were mistaken; i used the average current, not the peak current to calculate the stored energy - the corrected values confirmed returned energy equalled stored energy

i realise that you may be interested in the results of your proposed test anyway so i'll try to check that for you

the results used for this thread and in general on my tests with switched charge circuits are all obtained with the coil on a vertical axis

hi all,

what about the magnetic component?? could that be used to do useful work and still return close to 100%???

a very good question, dorro, - worthy of a test, thanks!

As I understand it, the official line on fly-back energy is that you only get back what you put in

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)
and is the basis for the success of the Adams motor and others.

It is an opportunity to be calculated for and aimed at.

anomolies can be attributed to the "tempic" field, which is the one that is perpendicular to the electric and magnetic fields
