Alnico magnets come in three main grades: 2, 3, and 5:
Alnico 2 traces back to the days of the 1950 Telecasters. This class seems to work well for middle-position pickups. It is known by its sweet, vintage tone, and there seem to be little disadvantages to using it.
Alnico 3 is the weakest of...

A Ferrite magnet is a category of permanent magnet. Its major constituent is Iron (III) oxide. It is the simplest of all existing permanent magnets and therefore also lower in cost compared to them. They are also used as magnetic cores for transformers among other applications. They are hard and...
The Ferrite permanent magnet is also known as a Ceramic Magnet and even as hard ferrite magnet. The name is interchangeable but they all refer to exactly the same material type. They are known as Ceramic Magnets because they are electrically insulating. Ferrite permanent magnets exist in two forms...
A permanent magnet is a magnet that is permanent, in contrast to an electromagnet, which only behaves like a magnet when an electric current is flowing through it. Permanent magnets are made out of substances like magnetite (Fe3O4), the most magnetic naturally occurring mineral, or neodymium, a...
