A question about per.magnets and lead

[giolvasrulez]

You are right about the lead. It was a text error. Lead has no permeability. Iron has good permeability and a 0.5cm thick iron blocked my neodymium magnetic field setup very well.
But high permeability alloy materials like mu-metal blocks entirely the magnet and also blocks hard component cosmic rays.
So I guess there has to be some major connection between cosmic rays and magnetism.

Hence, the magnetosphere.  Our shield drops....


We drop.

So what are cosmic rays exactly?

[giolvasrulez]

cosmic rays are just entering our earth's north pole (entry crown) and exiting earth's south pole (exit crown)..In the other areas around the earth they can't enter because they are blocked by a neutron "solidcloak". Ofcourse earth is a magnet.

[giolvasrulez]

Just try this.
Try put 2 iron plates (about 5 x 5 cm, 0.4 cm thick) in the center of the poles of a neodymium nickel coated small cylidrical magnet (1 cm diameter, 1 cm height).
It will totaly destroy the magnetic field in every direction.

I guess if it was possible to do the same to earth, by using magnetic shielding materials in the cosmic radiation entry and exit crowns (north & south pole) then kiss the earth's magnetic field goodbuy.
