Garry calls this the no Lenz motor. Lenz has always intreagued me and till today no one has drawn it in a way that I understand what it really is. So what I am primarily interested in is if Garry has beat the Lenz counter to motion force then how did he do it and does that give any clues to what it really is so that I can draw it.

So for starters read this so we are starting at the same point.

"Click here for more on the Lenz counter to motion force." Big lesson learning anomalie. Next I want to share what has puzzeled me for some time that is related. If you take a pendulum with a magnet on it and swing it and count the swings then place iron at the bottom center near where it swings past you will get less swings. We know as it approaches it is attracted and as it passes it is held back. And therefore we can deduce that the holding back force is stronger than the attracting force. Everyone assumes that the attracting force is equal to the holding back force but it is not. Back to Lenz. If a cored coil has current flowing there is a stronger magnetic force than just the iron core would have. And Lenz counter to motion force then kicks in just as described above with the magnet on a pendulum and the iron nearby.

What Garry does is several things

1. He has a no iron core coil which allows him to control the forces and time the forces.

2. He has 2 unusual flat coils (1 flipped around which changes the inter to outer wind to outer to inner wind). At one point I thought this may have been a reason for Lenz cancellation but after the tests below I don't think so. And the coil hole is almost the size of the magnet. And this geometry (5 turns by 20 layers deep ) may be a real factor too. Normally one would never waist current on a coreless coil because it makes a much weaker magnet for the current used.

3. He powers the coil circuit only on approach for attraction and I wondered at one point if Lenz was really on the leaving side only and thus Garry's discovery but below I don't think this is the case.

4. He used 2 neos on the ends 1 coil to get 2 amps of force for 1 amp of power.

If you sandwich two neos around these 2 Garry coils on a pendulum and short out the coil wires in either serial or parallel or one at a time you will see the Lenz counter to motion force causing less swings. So no wiring configuration has no Lenz counter to motion force. They all have it. So then what is it that might be no Lenz or low Lenz? When the coils are shorted there are 4 zones in a pendulum 1. left approaching to right 2. leaving to right 3. approaching to left 4. leaving. to left. So if Lenz occured only on approach that would explain why Garry has no Lenz counter to motion force. But the numbers later on do not indicate that is correct.

Another little magnet aside that fits in here too. Two attracting magnets only attract each other from certain positions. And the attraction occurs only in a flatened V area above one of the magnets. To demonstrate this take a board and cut 3 slice grooves with a hacksaw the width of 2 magnets you have ( round is better cause they roll ) and put to attracting magnets into the two slots and you will see that they actually repel each other when at the same edge plane. What one of those magnets really wants to do is jump up into the flatened V area and then jump on top of the other magnet. But you have prevented this by holding magnet from jumping up with the plastic strip and thus it repels. And with 2 1/2 inch round ceramic magnets the repel force is as far away as an inch.

So what does this have to do with the Garry design? Most motors have coil and magnet very close to each other near the same edge plane to get max forces. Well as I said Garry controls the forces with timing and if the timing is right the force above will not be there, thus making it more effcient. Oh yes one would think that the repel on the leaving side would balance this out but as I stated above I don't think so.

So I devised a pendulum with a very simple and easy to make switch to allow turning on the coil at approach or leaving time only. And this mechanical switch will have a spark which Tesla just loved to no end. Here you can see a close up of the switching which was the hard part of the design and the caliper magnets over the 2 flat coils in the back. The switch is simply a block of wood mounted off center so it stays in the off postion which gets tapped down by the arm where the wire touches the aluminum foil to make contact.

I understand that the Garry bottom line is using 100 watts but getting about 200 watts classic motor power. Verry good I'd say. Imagine what that would do for an electric car. And indeed the two magnets against 1 coil at each end could alone account for that.

Numbers that need interpretation. First we counted the pendulum swings without any wires connected and got 79. Then we shorted each coil and got 12 swings. Which means the Lenz counter to motion force is there in generator mode and I think would have to be in motor mode as well. We also changed to serial ( 2 coils wired + to - and + - according to Leedskalnin polarity rules) and parallel ( 2 coils wired + to + and - to - ) wiring and got about the same number. So you can see that there is Lenz counter to motion in this design. But that is not the same as Garry's design. So we then used the switch to limit the on time and did raise the swing counts to 21, 44, and 53 depending on the timing. But basically the closer to dead center the stronger the current will be and the stronger the Lenz counter to motion force is. So my conclusion is that the Garry design is not a no Lenz design but surely a low Lenz design. I also think that the big kicker is the one coil and 2 magnets on each end and also the 2 wimpy magnetic force air core coils powered in parallel certainly enhances the hertofore thought of wimpy magnetic force of air core coils.

The stick on the left is used to start the swings at the same spot everytime by kicking it out and letting it swing. "Click here for pendulum photo."

The arm is adjustable left and right for approaching or leaving timing. The neo magnet held plastic tripper tab is adjustable up or down to change the dwell. The two coils are epoxied into a hole in 1/2 inch plywood. "Click here for best see entire apparatus photo."

Greg Dunn's remake is much sturdier than my original. "Click here for Greg Dunn's improved pendulum. "

Greg Dunn's switch is the curved side of a tincan rubbing on an aluminum plate. The arm is easily adjustable but it is on in both directions.

I also made a knee like one way switch that pressed a microswitch down but only in one direction. This allow us to even power the pendulum and keep it swinging. The coils do warm up a bit when powering. A 1 amp battery charger will keep it swinging when set at 12v but it winds down and stops when set to 6 v. "Click here for Greg Dunn's improved pendulum. "

The knee switch works similar to a knee walking up a step which when lifted up is bent and thus kept free from hitting the step (in our case the micro switch ) but when set down then pushes - the micro switch down thus working in only one direction. So when the arm moves right to left the switch is pressed down because there is a stopper screw that locks the knee but left to right it is kicked out of the way because there is no stopper screw.
