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 100 mm, a width of 48 mm at the widest spot that tapers off to 31 mm, a depth of 6 mm and the bent bar is 12 mm wide.
The inner distance between the poles is 7 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.
This bent AlNiCo horseshoe magnet is 100 mm x 48 mm big (at the widest spot) and red-green coated.
As opposed to our other three horseshoe magnets, the arms of this magnet are not parallel and the ends of the poles are closer together.
