Design your magnet.
See the pull and other info about it.

Pull force is a planning estimate from grade and geometry, not a lab measurement. Actual holding force depends on the mating surface, air gap, and orientation — we'll confirm exact figures during quoting.

Surface field (Gauss) is calculated on-axis at the magnetized pole face — exact physics for axial/thickness-direction magnets, an approximation for diametric/width/length directions (marked "approx."). Real magnets vary by manufacturing tolerance; for sensor-trigger or other field-critical applications, confirm with a Gauss meter on a production sample.
