I think what you are looking for is "permeability". If so, would 100 Teslas be good?:

"The material with the highest magnetic permeability is Metglas Magnetic Alloy 2714A (Cobalt-based) [8] with a high frequency annealed permeability of 1,000,000 (Maximum DC Permeability (µ)). Hydrogen annealed (pure iron - N5 grade) can have a permeability of 160,000 (µ) but is very expensive."

http://en.wikipedia.org/wiki/Permeability_(electromagnetism)#Values_for_some_common_materials

Well i meant magnetic field per area, which is measured in Teslas http://en.wikipedia.org/wiki/Magnetic_flux

When no more flux can be accomodated in the core, saturation occurs.

So what i am looking for is material which can accomodate maximum  flux in same area per square meter.

The SI unit of magnetic flux is the weber (in derived units: volt-seconds), and the unit of magnetic field is the weber per square meter, or tesla.

I think permeability is a measure of how easy magnetic flux propagates thru the volume of the core.

Magnetic flux cares only about cross section, square meter of the core.
At least thats how i understand it.


Metglas Magnetic Alloy 2714A
General Properties & Characteristics
ELECTROMAGNETIC    
Saturation Induction (T)    0.57 Tesla

Metglass etc. offer very high permeability, but very low saturation.

2.4 T is quite good.  What material are you referring to that is 2.3 T?

Plain old 1018 steel (cheap/easily sourced) is 2.43 T (very good) but relatively low permeability.
Iron/Cobalt alloys offer both high saturation and high permeability, but are expensive, harder to source, and should be fully annealed for best performance.

See attached pics.

(P.S. PERMENDUR 2V would be a good material and can be sourced from hightempmetals

Hi

i meant Hiperco-50

If i use high saturation material with low permeability in static configurations with permanent magnets, it should not be a problem right?

If magnet is 1.5T, the 1018 steel core will recieve 1.5T as well, right...?

2.Do you know any company company, which offers 1018 steel sheets or laminates ?

Thanx

Just for info
A real:
N42 magnet is: 1.3T
and a N52 magnet is: 1.45T

Thanx

Metal Supermarkets, or Online Metals...

10 is for iron (steel) and the 18 stands for .18% carbon.

All cold rolled is generally 1018 and comes in rounds squares and flats, (plate)

But are you sure this is what you want? I doubt it is used for laminations.
