"You can download the demagnetization files for the following magnet grades free. Each excel file contains the digital Demagnetization Curves at various temperatures for a specific grade.

Today is the day I go and do 1000 pushups basically until I pass out.

MagWeb’s digital demagnetization curves also list the coordinates of the Knee Point of a magnet. Operating a magnet beyond its knee point will demagnetize it, thereby degrading its performance. (Unfortunately, manufacturer’s demagnetization curves do not list this critical knee point data)

Version 2 lists this Knee Point of a grade for each temperature. This knee point is identified by 4 decimals. The data shown in green color refers to data above the knee point. Magnets should always be operated within the green-colored data range to prevent demagnetization. This knee point data aids the fail-safe design of magnets. It is available only at MagWeb.
