Studying Shielding, needs some advice

[Originator]

I notice some shielding effect on my microwave door.  The door is glass over a pattern of holes drilled in some type of painted metal.  The magnet is attracted to the door, however if the magnets are held at the same distance from the door, there is a neutral zone that allows closer proximity with less force than without the door in between.

Maybe the holes are the trick.  Can anyone else test on their microwave doors to see if there is any shielding effect?

JamesRoy, on U-Tube, has videos on shielding which I've found intriguing enough to look into.  If he's here in these forums please let me know how to contact him.

To me, it's not about making a magic wall that completely blocks all effects of magnetism.  It's more about redirecting or reshaping the magnetic field in such a way that a magnet motor could run without having to add electricity to an electromagnet in order to get past a sticking point or gate.

For instance, would it be possible to drill angled holes in a thicker shield to "direct" the magnetic field from the magnet behind the shield?  Also, I like using the shield to attract the stator and having an opposing magnet behind it.  In theory, once the magnets have passed each other, they should repel each other and turn the motor.  Maybe it's about getting the thickness of the shield correct so that the attraction is enough to bring the opposing magnets toward each other far enough that when they finally do repel each other they keep the motor going in the direction it's supposed to be going.
Or, if a shield can be used to drastically reduce the repulsion encountered once the motor has come full circle, it might be possible to get the stator back into the starting point.

One thing is for certain.  I haven't seen nearly the work done on shields that I have on the magnet motors themselves.

Hi,

James Roney is a member here too      See his thread: http://www.overunity.com/index.php/topic,4528.0.html

I think your way of thinking on the role of shielding is correct. By covering one side of a permanent magnet with a highly permeable material (like with transformer laminates or permalloy or soft iron pieces etc) the flux gets more or less confined  and guided mainly in the shield while the opposite side of the same magnet remains open hence the flux over there though also changes can remain stronger.  James nicely shows this in his videos.
I also believe that using such partially covered magnets in a suitable arrangement as rotor - stator components a magnetic motor can be built. Maybe James has been on such setup since his videos...

James Roy hasn't posted on this site for a few months.  I PM'd him.  We'll see if he gets back to me.

If a magnet in repel mode can be "aimed" through shielding I don't see why a permanent magnet couldn't replace an electromagnet in the magnet motors that are up and working now.  Might be a matter of hitting the sticking point with just enough repulsion to break the attraction loose, or at least weaken it enough that other stators pushing rotation can overcome what's left of the sticking point's effect.

These motors are very close to both working and being capable of useful work, like generating electricity.  We've just got to stay with it for a bit longer.
