Bar magnet rectangular long

100 x 15 mm, school magnet made of AlNiCo5, red-green coated

Item number	EDU-8
Unit of Sale	1 piece

Description

This long cuboid AlNiCo bar measures 100 mm x 15 mm x 10 mm and is painted red-green. The poles are on the small areas with 15 mm x 10 mm, the north pole is located on the red end. This magnet is great for demonstrating the magnetic field of an oblong magnet.

Almost all magnets on our website are made of NdFeB (neodymium-iron-boron). However, this school magnet with its coloured poles is of a different material, namely AlNiCo (aluminium-nickel-cobalt and iron). AlNiCo is well suited for educational purposes because it is less brittle and therefore less fragile. Though AlNiCo is approx. eight times weaker than NdFeB, it is still much stronger than a ferrite magnet (=refrigerator magnet).

Additional features and tips

That's how the magnetic field of oblong bars and rods looks like. Iron filings are well suited to visualize magnetic fields.

We thank Bram Spaan, photo artist from the Netherlands, for these great photos with different AlNiCo magnets (www.bramspaan.com).
