Magnet Selection Tools
Pick a material and grade, estimate surface field and pull force, find the nearest grade from other makers and convert units — free, no sign-up. Our engineers check any selection for free.

NdFeB, SmCo or ferrite? Get a grade and coating recommendation from working temperature, environment, cost and space.
Surface Field & Pull Force Calculator
Estimate the surface gauss and pull force of disc, block and ring magnets by size, grade, measuring distance, air gap and working temperature.
Magnet Grade Cross-Reference
For each AIC grade, the nearest published grade by Br and HcJ (not an official equivalence) — NdFeB vs MMPA, VACODYM, Shin-Etsu, NEOMAX, NEOREC, Arnold; SmCo vs MMPA, VACOMAX, Shin-Etsu, Hitachi, RECOMA; ferrite vs MMPA, C-classes, TDK FB.
Magnetic Unit Converter
Gauss ↔ tesla, oersted ↔ kA/m, MGOe ↔ kJ/m³, kgf ↔ N ↔ lbf and inch ↔ mm, as you type.
