New and stronger then ever magnet created !

They invented a new magnet but where should they Use it for ?

The LHC uses magnetism and the maglev. etc
What technology is available but in need of stronger magnets ?

Anyway another accomplishment for humankind.
Here are the links.

Iron-nitrogen compound forms strongest magnet known

A group of scientists from the University of Minnesota say that Fe16N2 crystals are more magnetic than the most magnetic material previously known, and its magnetism exceeds the predicted limit of magnetism for a material.

Strongest Magnet Ever Created in the Lab

In a groundbreaking experiment, investigators at the University of Minnesota, in the United States, recently managed to create the most magnetic material on the surface of the planet. In addition to this achievement, the group also managed to demonstrate that the predicted limit of maximum magnetism for an object can be indeed exceed. In their investigation, the specialists used iron and nitrogen compounds, a mix of which, called Fe16N2, was found to be the Holy Grail of magnets.

Can anyone say Magnetic powered bullet train?

That would be a dream come true.

this should increase the efficiency of adams type motors considerably.

and they already have a COP value greater than 1.

I wonder if it is stable? If so, this is tremendously important. The strongest
magnets now depend on Rare Earths which have two problems. They are
rare and China has a monopoly on supply.

The ingredients are cheap. Could we see a golden age of permanent magnet
motors?
Cheap electric cars, cheap wind turbines?

I'm not even speculating about Over Unity stuff

Stronger magnets means smaller electric generators can be made to output the same as a larger one.

I'll admit I just scanned the articles linked instead of doing in-depth research, but I am wondering what the magnetization level achieved was? It's strange to me that this one measurement, the one they are excited about, is missing...

That said, a very interesting development! The potential for further study into magnetic properties (a sorely lacking branch of physics) is huge.

Allready exists you no a bullet train on magnetism . It is called a maglev.
Created by the Germans and up until know only in put use by China.

Like isn't that a perpetual motor ? Are those not still considered a pseudo science ?

reply to post by Sinter Klaas


Yeah, Obama wants to build one. We will see how that goes.

The applications for vehicles i am sure would also be looked into, if it has not already occurred.

I know China and Japan have Magnetic Tech that i envy

Perhaps an improved Magnetic perpetual energy device?

The Dutch source states it is about 18 % more powerfull then what they used to believe whas possible. ( Best possible translation )

I recently learned that there aren't even enough resources to build 2 million prius automobiles. After that finito.
China has indeed a monopoly on those resources. And the waste whats left is also not a pick nick.

reply to post by Sinter Klaas

Yeah, I saw that. But what one group believes is possible is not necessarily the same as what another group believes is possible.

For reference, the NdFeB Grade N42 magnets I am working with right now are putting out about 1.3 Tesla.

I think the theoretical limit is 2 Tesla. They are claiming to exceed that by 18%.

I could be completely wrong.

Wow easy with the science.
Please explain a Tesla for me ? I know it has something to do with a magnetic field or something. But I have no idea how to see, link or grade it

I might be mistaken but it seems like rather than creating a new method to develop Fe16N2 magnets they just used a better method for testing the sample.

A 'Tesla' is a unit for measuring how strong a magnetic field is. A 1.3 Tesla magnet is massively strong. MRI machines operate at somewhere around that kind of strength, to give an idea of how strong that is.

Indeed as other have stated, 1 Tesla is very strong. In fact, the earths magnetic field doesn't even match 1 Tesla.

From Wikipedia:

The strength of the field at the Earth's surface ranges from less than 30 microteslas (0.3 gauss) in an area including most of South America and South Africa to over 60 microteslas (0.6 gauss) around the magnetic poles in northern Canada and south of Australia, and in part of Siberia.

Because the unit Tesla is so large, they came up with a smaller unit called Gauss.

1 T = 10^-4 Gauss.

The magnetic limit was proposed because scientists believed that there was a theoretical limit on how strong a permanent magnet could be, without destroying the magnet itself.

So far the strongest man made electromagnetic field in a lab is of the order of 40 Tesla.

The strongest permanent magnet consists of Neodymium Iron Boron (NdFeB or NIB) and as of now they can only achieve around 1.4 Tesla.

According to popular science, "By combining a conventional electromagnet and a superconducting magnet, the National High Magnetic Field Lab hopes to produce the highest steady field ever achieved, 45 tesla"

This is of course a steady field electromagnet. They have also produced things called Pulsed electromagnets, which are momentary and not steady. These have reached upwards of 850 Tesla for very very short bursts. Again though, these are electromagnets, meaning they are produced via a current.

To put it into perspective, the LHC uses magnetic fields of around 8.5ish Tesla.

The implications of stronger solid magnetic material is far reaching. Just about everything to do with electricity is in some way shape or form due to a magnet utilizing magnetic induction to create currents.

Just about everything to do with electricity revolves around magnetic fields, well... rather, revolves within a magnetic field!

i have seen a small scale adams type motor drawing .4 of an amp at 12V and putting out 1.6 amps at least with the same voltage. it ran off a half charged battery and charged that battery back up to full.

here's a free e book with an absolute wealth of material. 2,100 pages.

enjoy

I hate to burst some bubbles but there is another application.

Do you remember the movie eraser?

Hand held railguns become possible.... I wonder if the filed for patents yet?

ECM become deadlier as does the material for UHF & ULF weapons

then the beautiful part, space travel!!!!!

If you read this

arxiv.org...

They claim a maximum saturation of 3.5T. I assume that means 3.5 Tesla.
