I guess the lack of response to this "awesome and fantastic videos" is more related with the fact that there is nothing "awesome and fantastic" to see there anyway.

As long as people misunderstands what we are dealing with, and we all misunderstand it when it comes to magnetism, these kind of mistakes will be repeated one after the other.

First, there no such a thing as a magnetic shield. You only can modify the field and flux lines, so only it appears to be shielded, but in reality the mag field is just greatly distorted and with a big low flow region.

Don't be mistaken. I am sure that magnetism can be used to produce free energy. But the so called shielding is a dead end, and to get energy from magnets requires a completely different point of view

Just my two cents.

I was hoping that pure tin (as opposed to tin-plated steel) was the "magic bullet" here.  Perhaps not... :'(

Sorry, misquote.

Like poles repelling on one side and like poles not repelling when flipped.

I am not very good at physics, and respectfully believe you have a greater understanding than I do. A thought came over me, and please understand this is off the cuff. I remember looking at a Tri-force gate, or something like that. Isn't this getting past the sticky point? Wish I understood these things more.

Hi critics,

Something is bothering me.

From:
http://www.supermagnete.de/eng/magnets.php?group=blocks_big&switch_lang=1

BTW :a very serious  company, IMHO. )

Neo magnet number :

Q-51-51-25-N
50,8 x 50,8 x 25,4 mm
Weight: 500 g
Nickel-plated
Magnetisation: N40
Strength: approx. 100 kg
......
 1 pc.   39,50  EUR ea.

We call this magnet the DEATH MAGNET.
I have no idea what you can reasonably do with this magnet - it is simply too
intense for most any use. Monitors, credit cards, video tapes - all down the
drain. Tip: Only use this one with a thick piece of cardboard between it and
the metal surface, otherwise you'll never be able to get them apart again. My
advice: buy a smaller magnet! But when you think you really must have this
monster: BE CAREFUL!!! And please never, never allow children to play with the
Death Magnet.

---------------------------------------------
1" = 25.4 mm.

50.8 mm x 50.8 mm x 25.4 mm =  2" x 2" * 1" = 4 cubic feeet

Now, according to the vid n?2, this guy is using a
4" x 2" x 1/2" = 4 cubic feeet Neo magnet.

So, this guy is claiming using a Death Magnet!
Question: How are his fingers

So, that's it??

I saw this thread when it first opened a couple of days ago. I've just got back and expected to be reading a few pages to catch up.
What a disappointment. I might try something but all I have are flat and round neos. no cubes.

Sorry mate i found the video and to my understanding this was a way of getting past the sticky point so i posted it, even tho im a little skeptical myself i was hoping for a few more posative responces but i guess until one of us has a go at sheilding the magnets there is always gunna be skeptics.

The problem when trying a motor of this type is the lack of continously thrust forward.
Between each magnet passage there is an area of no thrust. This is where the motor
will find equilibrium, no matter what. In a true and really real working motor there is always a
force thrusting forward, even when loaded hard or stalled. When you stall the motor and release it,
the rotor must immediately start to spin on its own. Powerful stall torque is absolutely crusial.
The strength of the stall torque vs the maximum free spinning rpm at no load determines
how much power can harvested from a generator connected to the shaft.

Yes, but still the sum of thrust and nothing, is still thrust. I believe the case is more that the thrust is cancelled by an equal counter thrust after the area of no thrust. Well, not perfectly correct. The thrust or force will over a given distance provide the amount of energy required to run a motor. So the greatest thrust at one side can be greater than the greatest thrust one the other side, but the difference is over how long distance the average thrust is distributed on each side. That's why the magnets allways will find equilibrium. Thrust or force isn't energy alone without the distance. Say we have an average trust of 10kg over a distance of 1 meter, this is the same energy as 20kg thrust over a distance of 0,5 meters

The realization of thrust or force is often not being connected with a given distance the force is distributed over - which in turn is the most common misapprehension when speaking of provided energy. Probably one of the explanations why there is nothing more than failed magnet-motor projects out there.

Our farm tractor had an opening in the front where you could insert a crank to start it.

It always struck me how the flywheel seemed to be imbalanced...it would turn very hard until it past a certain point, where it would speed up with such force that if you were not careful the crank would  also make a very violent rotation.

Would a weight placed on a rotor at the correct location be enough to take a magnet motor past the sticky point...and with torque ?
