The whole-earth catalog
Coded (programmable) magnets that align, latch, spring and hold on purpose — ours, in stock. And every standard magnet behind them: neodymium, ferrite, alnico and samarium, in block, disc, ring, sphere, cup and sheet, from the makers who make them. One catalog for the whole field.

The everyday magnets a project needs. We do not make or stock these — we point you to real listings from vetted makers and earn an affiliate commission. They are made and shipped by the seller.
