Overview - Alnico Cylindrical Bar Magnet

Alnico rod magnets / Alnico cylindrical bar magnets / Alnico cylindrical rod magnets

The alnico rod magnets are also known as alnico cylindrical magnets, alnico cylindrical bar magnets and alnico cylindrical rod magnets. They can be used at temperatures of up to +550 degrees C.

They are termed bar magnets because the distance between the poles is greater than the pole face dimensions (i.e. they are magnetised in the same direction as their longest dimension). The alnico cylindrical bar magnets are supplied as either red painted or natural finish (uncoated, unpainted).

These alnico rod magnets are very popular of sensing applications and for experimental use in schools. The alnico cylindrical bar magnets can be offered in other dimensions and grades. We supply custom made alnico magnets. You can have other colours as well if you wanted e.g. black.
