MAGNET SHIELDING

[24hosting]

I came upon magnet shielding. Has any one tried this ?. I am going to ,but if someone has some first hand knowledge about how ..or if this works with a magnet motor I would appreciate the feed back. Thanks. 24hosting.

I know of nothing that will act as magnetic shielding. There are two types of materials that interact with magnetic fields. Ferro materials, iron etc... and Diamagnetic materials like copper and aluminum. In a magnet motor, if iron is used, the magnets get strongly attracted to the iron. If copper is used, there is a slight repulsion and as the magnet moves faster the repulsion (opposing the movement) gets stronger. So using either of the two types of magnetic materials actually hinder the effect you want to achieve. Youtube has a few video's showing failed attempts. Here's one.

Edit: Well you could say that putting a magnet inside an iron enclosure would do it but to get the magnetic field back you would have to pull the magnet out of the enclosure and that takes work.

The ferromagnetic material can divert the return path of the magnetic field.  The ferro material must have both a north and a south pole attached to it in order for it to divert the return path.  If only one pole is attached to it, then the field will pass through or be pushed around the ferro material.

Here are a few of my videos showing how shielding works if properly done.

The ferro material is acting as a wire for the flux to travel through.  The interesting thing about using this principal is the flux can now be viewed as an electrical current that can be confined and should be able to be exploited.  Here is an excellent thread showing how to exploit this phenomenon by confining the magnetic field with a ferro material and using an outside circuit to provide torque on this confined field without any BEMF, http://www.overunity.com/index.php?topic=8461.0

Trying to use it as a shield is a setup for failure unless you are trying to protect parts of a device from the influence of the magnetic field, such as hard drives.  IMO, it has a huge potential in magnetic field confinement along with an external electrical current as shown in the link of the above thread.

I found something interesting with ferrofluid. When a magnet is covered by this ferrofluid, averything none magnetic materials is repelled away from the magnet as long the object is inside the fluid. The virtual mass of the ferrofluid close to a magnet is so high that everything will be pushed away inside the fluid. So there you have a very powerful diamagnetism involved - virtually speaking.

So what if you put a solid magnetic material, which have the same mass and magnetic properties as ferrofluid, inside the ferrofluid, and experiment with different positions just to see if you'll find a way to force this magnetic piece in one direction, or in circular motion, by finding a balance between its buoyancy in the ferrofluid and the magnetic attraction to the magnet. This balance between attraction and buoyancy I believe is some kind of magnetic shield that comes into work instantly as the magnetic piece is "entering" the ferrofluid. Maybe this is a way to "trick" the force on the magnetic piece to make one-direction force?

Well, everyone here knows that magnetic shielding is the key to perpetual motion. How are the researchs in this field?

When will the world know a magnet that attracts steel balls only at one of its sides, and not at the other side? When humanity will discover the "unidirectional attraction" magnet?
