I have drawings of magnets with physical dimensions, materials, tolerances, etc. How do I add a Magnetic Flux requirement (weber, volt second) so I can measure the magnet when is arrives and be sure that it is fully magnetized? I know how to add this to the drawing literally however where do I...
Does anyone know where I can get a magnet characterized for all four quadrants. Electron Energy use to offer this service but it doesn't show up on their website any longer.

I’m looking for some help with respect to skin effect. On a PM synchronous motor, the windings are subjected to the rotational frequency from the PM rotor and to PWM frequency that is driving the motor. I feel that the fundamental frequency of the rotor is the main contributing factor to skin...
I'm looking for information about a winding machine for large diameter wire in a DC armature. I have seen this machine (a long time ago) and I think it was called an "Able" winder. It doesn't wind in the traditional sense (fly, needle, shed, etc.), instead you have to cut the magnet wire to...
I am magnetizing as an assembly.
In some materials you may get 95% of B but only 50% of H, so not good.
How can you have this situation?

This is from ExcelCalcs . . . However, it does not automatically update as you make changes. You have to do it manually. For me, not such a big issue.

If you are talking about the equation format, they could have been using ExcelCalcs (https://www.excelcalcs.com/). I believe there are others as well. I've used ExcelCalcs for many years. It displays EXCEL formulas as equations.

Thanks, I understand but I am curious as to how the published data is determined. In other words, what does he magnet vendor due to establish the values they publish?

If I subject unmagnetized Neo to elevated temperature but stay below the curie temperature will this adversely affect the magnet when later magnetizing? In other words, will I still be able to fully magnetize the magnet after it cools?
