Notice that the multiplier is 4*pi and a power of 10 if you are looking for
precision. I use 79.6 for meaningful engineering work that I deal with.

The tricky part is making sure that the conversion is the right direction.
1 A/m = 0.01 A/cm
If you have oersteds and want amperes per meter, multiply by 79.577
If you have amperes per meter and want oersteds, multiply by 0.01257

Group:
I want to make sure I did this right.
I was trying to determine the permeability of this material.
The B-H curve shows Flux density B in Teslas. (1 tesla = 10,000
Gauss, )
But the Field Strength H is in A/cm. How do I convert this into
something I can use like Oersteds or A/m?
No guessing, please. I would appreciate hearing from someone with
experience dealing with these units.
Arun? Hans?? Are you out there?? help!!
Regards,
Lou
