Pulsing a Permanent Magnet on/off

Pulsing a Permanent Magnet on/off

I think most of us will agree that if one could pulse or turn a PM on/off with low cost on the switching mechanism, we will have OU.

I haven't found a way to turn a PM on/off, but I think we can emulate switching a PM on and off by using a ferromagnetic material instead of a magnet. A ferromagnetic material can act as a PM in every way.  We will refer to this ferromagnetic material as a metal for simplicity sake.

We can easily switch the metal between the two following options:

1)  Attract a magnet and not attract another metal piece.
2)  Repel a magnet and attract another metal piece.

I'll post a drawing or a video on how we can switch between the two options at little to no cost using a magnet whose only purpose is to control the switching (this could also be accomplished with a magnet and reed switch).  Before I take the time to create a drawing or video, I would like to know first if this has any potential in working. 

To have the metal to repel a magnet is easy.  Place two magnets with the same pole's attached to the front side of the metal.  With this arrangement the backside of the metal will repel another magnet at a distance and will attract metal.  Now, turn one of the magnets over so a north pole is attached to the metal and a south pole is attached to the metal (both magnets on the front side of the metal).  With this arrangement, the backside of the metal won't attract another metal piece and will attract a magnet.

This is not difficult to understand.  All we are doing, is substituting some of the magnets with a ferromagnetic material, which can emulate a magnet, that we can control in order to simulate pulsing or turning a permanent magnet on/off.  The thickness of the metal must be matched to the strength of the magnets that are attached to the metal in order to obtain the desired results.  There is a simple technique to matching the thickness of the metal to the magnets, which I will share if there are those who want to build and test.

Let me know what you think.

Thanks,

How about reconditioning the magnet like what floyd sweet has done in his VTA.

try to search floyd sweet VTA

Hi GB

Maybe you are also aware of Naudin tests on a very similar setup you have just described.  See this link:

http://jnaudin.free.fr/html/mep1.htm

The setup you describe and that of Naudin's both surely works, (I tested Naudin's setup some years ago)  the question is how to utilize them in a useful arrangement, keeping the input power at a minimum possible for operating them while making advantage of the flipping and/or increased flux lines in the arrangement,

I am all ears to seeing a drawing on your setup.

Hi GB, you may already know this, but Butch LaFonte has made excellent strides in this area.  Worth looking into.

So you'll make temporary "permanentmagnets"?
