• Discs – https://craftyarts.co.za/product/neodymium-rare-earth-disc-magnets

Being part of the rare earth magnets group, these magnets are the most powerful permanent magnets produced commercially. They are powerful and compact size. A small magnet that weighs only 2 grams has a holding power of 1700 grams.

The Neo magnets are brittle and can corrode and are therefore normally nickel-coated. They are the most popular magnets due to their excellent power and compact size.

The strong magnetic properties make the neo magnets ideal for schools and science labs for testing and experimentation.
