Magnetic wheel by steel shielding

[nix85]

Magnetic field is non physical entity hence it cannot be blocked by any material object.   Magnetic materials like iron do not block magnetic field but provide path of least resistance to magnetic flux to reach the other (opposite) pole.

If at all a magnetic field is to be blocked,  it can be done only by using another non physical field.   Is there any field which can block magnetic field?

Physical? There is no such thing as physical. All is one energy field cascading all the way
down to "matter".

I know well ferromagnetic materials do not block but redirect the magnetic field, i think this is the second time you mention this as if every 5yo does not knows this.

I did not say it blocks it, i said it apparently absorbs it without being attracted or repelled by it.

There are also subtle aspects of magnetism like A-field and Aharonov Bohm Effect.. You can not speculate or come to conclusions without taking these into account.

In layman's terms, charged particle can be affected by a electromagnetic field altho it is not inside the field.

Conventional physics calls the carrier of the magnetic flux virtual photons which is not that far from truth but they also do not understand magnetism nor the energy creating it.

Why else would he need a stack of 8 magnets to repel a single magnet?

When you stack magnets like that, after second block there is no increase in field strength.

Again, watch closely, the edge of that material attracts the magnet

It's strange, if it was ferromagnetic it should attract anywhere, not just on the edges.

Maybe outer layers are pyrolitic carbon and inside neodymium powder but diamagnetic effect is not that strong. Who knows.

Few years back i was very much into this shielding thing (when i thought it's needed), i had a bunch of ideas.

One idea i liked a lot was two blocks made of many small neodymium blocks N S N S.. say 100 of them. Two blocks in repulsion so that each N is facing N and every S is facing S inbetween the blocks, two blocks being forced together with epoxy or whatever.

Since there is equal number of N and S on each side average polarity is 0 relative to the big magnet passing by, but flux of the big magnet cannot pass through the block cause they are in repulsion.

So say big N is approaching such block, it's flux would all focus on the 50 small S neodymiums.

But just behind them is opposite polarity repelling the big N.

So question is would big N ignore all the small magnets repelling it on both sides and just link with 50 small S attracting it, or would the attraction and repulsion cancel out which was the original idea.

I tend to think it would lock up with the 50 small souths and come to stop.

Then, there are similar ideas on youtube with balancing repulsion between same poles with layers of ferromagnetic material, but things get tricky at various angles.

Remember the Don Smith's generator that allegedly worked in similar fashion.

He never revealed exactly how, he said in his lecture (on youtube) that it's a vinly LP cowered with "metal powder". I once corresponded with late Patrick Kelly and he claimed Don said it was neodymium powder in one of his lectures, but this would obviously not work. He probably misremembered the "powder metal" for "powder neodyimium".

Don also claimed on his old site crazy power output for this device below (unless his site was hacked as PK told me which i doubt) like 50kW per coil or similar.

I was totally into this device, still love it's design.

A-field

I did not say it blocks it, i said it apparently absorbs it without being attracted or repelled by it.

The shield absorbs flux from left magnet and holds it on left side,  also absorbs flux from right magnet and holds it on right side.  The repelling flux on left and right side stay within the shield without repelling.  Is that so?
