Electromagnets repelling permanent magnets:
There is no test data available, due to too many variables on permanent magnets. For how-to-select permanent magnets see guideline at Application Notes.

 

Safety Caution:

The holding values as listed are actual readings of breaking away a 1/2" steel plate with no air-gaps between them. They have not been de-rated. For safety in holding applications, do not use electromagnets at more than 1/2 of rated value. In lifting applications, do not use at more than 1/4 of rated value. Do not use electromagnets over people.
