Almost all magnets on our website are made of NdFeB (neodymium iron boron). These school magnets with their coloured poles are of a different material however, AlNiCo (aluminium nickel cobalt as well as iron).
AlNiCo is suitable for educational purposes because it is less brittle and therefore less breakable.
However, AlNiCo is approx. 8 times weaker than NdFeB, but still much stronger than a ferrite magnet (=refrigerator magnet).
Here you can see all our red-green coated AlNiCo school magnets at a glance:

That's how the magnetic field of oblong bars and rods looks like.
Iron filings are well suited to visualize magnetic fields.
The long block-shaped AlNiCo bar is 100 mm x 15 mm x 10 mm big and red-green coated.
This magnet is suitable to demonstrate the magnetic field of an oblong magnet.
The poles lie on the small areas with 15 mm x 10 mm.
