AlNiCo Horseshoe Magnet

AlNiCo Horseshoe Magnet

Horseshoe magnet, also known as c-shaped magnet or u-shaped magnet, is a classic AlNiCo magnet shape that has long been recognized as the most universal symbol for permanent magnets and magnetism. It can be manufactured by either casting or sintering, but almost all AlNiCo horseshoe magnets are cast AlNiCo magnets. In the beginning, These magnets were primarily used for holding applications, but are now primarily used as educational facilities to demonstrate magnetism and magnetic fields.

Shape Factor

The AlNiCo horse magnet shape was initially designed as a replacement for the AlNiCo bar magnet because it produces a much stronger magnetic field. The N and S poles of a horse magnet are in the same plane and adjacent to each other, allowing magnetic flux lines to flow in a relatively direct path between the two poles and concentrating the magnetic field. These magnets can significantly reduce demagnetization in addition to increasing pull force. Pc of AlNiCo disc magnet or AlNiCo ring magnet is weaker and slightly higher in AlNiCo rod magnet or AlNiCo block magnet. The horseshoe shape is an extreme version of an AlNiCo rod magnet with an infinitely long length and a high Pc value.

Advantages

High temperature stability

Resistance to corrosion

High coercive force

Good magnetic properties over long periods of time

Disadvantages

Relatively low magnetic strength compared to other types of magnets

More expensive than some other types of magnets

Brittle and can crack or break easily

Overall, AlNiCo rod magnets are useful in many industrial applications that require high temperature stability and good resistance to corrosion. However, their relatively low magnetic strength and higher cost compared to other types of magnets should be taken into consideration when selecting a magnet for a specific application.
