The AlNiCo horseshoe magnet is 100 mm x 63 mm big and red-green coated. The north pole is located on the red end. The horseshoe magnet is well packaged for shipping, the poles are short-circuited with a magnet keeper. These classic horseshoe magnets are popular in school experiments.
Almost all magnets on our website are made of NdFeB (neodymium iron boron). These horseshoe magnets are of a different material however, AlNiCo (aluminium nickel cobalt as well as iron). AlNiCo is better suitable for horseshoe magnets because it is less brittle and much more heat-resistant (up to approx. 450 degree Celsius). However, AlNiCo is approx. 8 times weaker than NdFeB, but still much stronger than a ferrite magnet (=refrigerator magnet). A NdFeB magnet in a horseshoe shape would break too easily and therefore is not produced in this material.
