What would be the ideal magnetic characteristics to have an independent test facility check to qualify new suppliers of permanent magnets. I would have them perform a B-H curve test and provide a Hysteresis graph of the sample at the temperatures I'm interested in. Some vendors will provide a representative Hysteresis graph for a single lot of magnets (in small quantities), but I am interested in an unbiased independent test.
I would also have them test the plating of NdFeB magnets to insure that they have a good process. I really don't know how to ask for this other than to slice the material and observe the interface of the layers.
I know that any testing I have done will not necessarily be representative of the repeatability of their product, but I would like to know that they have at least provided the material with the properties that I have ordered.
Any suggestions will be greatly appreciated.
