Magnet coil cores, demagnetization power and Lenz delay.

Yes is correct, i would like to see the corrections in my circuit and perhaps i can make other experiments...! i am working in a mechanical switching  to charge a larger capacitor, i hope i can make it, because i burned 3 big reed swtches very fast....!

This is my second driver circuit, i hope it serves for the corrections....!

Jorge,

attached please find the modified circuit for "charging a battery" and for 24 V operation (2K in front of Hall sensor and 10 K resistor as a Voltage divider for the base of the MOSFET).

I do not believe in mechanical switching.  Put a 0.1 µF or 0.2 µF capacitor parallel to the mechanical switch to make it last longer.

For feeding back to the drive battery just take away the "charging battery" (only a diode from MOSFET DRAIN to the positive rail), but it will not work. Unfortunately I do not know how to successfully "feed back" the "self inductance of a coil" to the drive battery. I think nobody knows.

Conrad:

I hope that when you use a diode to direct the discharging energy from a coil that you look at your schematic and work out how the current will flow.  Don't make any assumptions, that's unwise when you discuss electronics.

The Ossie motor multiple-diode configuration can route the coil discharge energy back to the source battery.  It may give you a longer run time because of that but that's all, there will be no magic.  I know that many people built replications and had hopes of over unity but that was never going to happen.

Conrad and Jorge:

Your new schematic will charge the charging battery.  If you are interested you should measure the power the supply battery puts into the motor, and the power that goes to the charging battery.  Comparing the two gives you some meaningful data.

Beyond that, as Farmhand has stated in the past; a motor that just spins and has no useful output does not really do anything.  So that's something for you to think about.  Is there any interest in building some kind of motor that does something useful?

can be done but how?
