Magnetic field change with no drag?

[sparks]

  I see a common thread amongst the devices working with electromagnetics.  Most of them are getting around Lenz's law.  If you put a permanent magnet on say a child's swing set.  Then on the ground under the swing you put a coil with high inductance.  Then we get the swing going.  As the swing passes over the coil the coil experiences a magnetic field flux change.  According to Lenz's law this will induce a current whose magnetic field will counter the change in magnetic flux.  The big question is when?  If the reactance of the coil is such that the swing is way past the coil when the current flows what drag will it effect on the swing momentum?  The seeming overunity comes from the electron intrinsic energy.  Physicists describe the electron as a spherical standing wave.  If we upset this resonance then we gain energy that was being stored in the standing wave.  Nature is quick to restore the resonance of the electron and we are back in business.

Hi,
Depends when excatly you draw current from the coil.
Also with bigger coils you could use the large RL time constant
so you might have almost 90 degrees phase shift between current and voltage.
Maybe you can use this in your favour somehow.

If you know, how, please post.
Many thanks.

   The current could charge a capacitor (gated through a diode) and  be drawn off as needed by a load.  It could also be the primary current in a current transformer.  What I see is an alternator whose load current doesn't flow until the field pole has already gone by.  Or a magnetic field flux change that is induced by radiated energy.  The resultant voltage rise creating a countering magnetic field but either too late or too far away to effect the prime mover.  In other words time shifting or phasing the counter magnetic field out of the picture.  The energy is stored in the coil and released when it effects the magnetic pulse generator the least.

you got me thinking about swinging  so i Googled it and got this

An improved swinging type generator for use in automatic wrist watches is disclosed. It contains: (a) a base with a center shaft hole, (b) a stator mounted on the base containing at least one layer of ring-shaped coil plate having at least one periodic-wave-shaped induction coil arranged on and along a circumference of the ring-shaped coil plate; (c) an unbalanced-and-weighted swinging magnetic rotor having a central rotary shape. The rotary shaft is mounted in the shaft hole of the base, and the unbalanced-and-weighted swinging magnetic rotor includes a magnetic ring having a plurality of magnets arranged in a head-to-tail manner along a circumference of the magnetic ring. In a preferred embodiment the induction coil has the shape of a multiple-cycle square-wave, and the angle of the square wave equals the magnetic angle, which is the angle formed between half of the arc length of an individual magnet of the magnetic ring and the center of the shaft hole, so as to maximize the electro-motive force that can be generated. http://www.freepatentsonline.com/5684761.html

 powercat, that was a great find and I found a bit more about it but I would like to see some pictures and or drawings.

The next link is what I could find.
