Horseshoe magnet small

50 x 40 mm, school magnet made of AlNiCo5, red-green coated

Article ID	EDU-3
UoS	1 piece

Description

The AlNiCo horseshoe magnet is 50 mm x 40 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 as the magnetic field becomes visible with iron filings.

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.

Please note

The horseshoe magnets are not evenly magnetised over the full length. Only the tip of the magnet has a clear north or south pole. Therefore, if you need a rather big and homogeneous field for your experiments in class, you are better off with two normal neodymium block magnets placed opposite from each other.
