EDU-4: Horseshoe magnet (medium)

The horseshoe magnet is well packaged for shipping.

The poles are short-circuited with a magnet keeper.

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.

The horseshoe magnet has a height of 80 mm, a width of 61,5 mm, a depth of 16 mm and the bent bar is 8,5 mm thick.

The inner distance between the poles is 44,5 mm.

Here you can see all our red-green coated AlNiCo school magnets at a glance:

The magnetic field of a horseshoe magnet can be well illustrated with iron filings .

Caution: The horseshoe magnets are not evenly magnetised over the full length for technical reasons. Only the tip of the magnet produces a somewhat homogeneous field between the pole endings. So, 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.
