- The Alnico 8 bar magnet is installed beneath steel pole screws, slugs, or blade pole pieces inside humbucker and high-output pickup assemblies.
- After magnetization, the bar magnet transfers magnetic flux through the steel pole structure toward the guitar strings positioned above the pickup coil.
- When the steel string vibrates, it changes the magnetic flux distribution around the pole piece, and the surrounding copper coil winding converts the flux variation into electrical signal output.
- Compared with Alnico 5, Alnico 8 provides higher coercivity and stronger magnetic pull, producing a more concentrated magnetic field and increased pickup output response in high-gain pickup configurations.
Custom length, width, thickness, and magnetization orientation can be manufactured according to pickup structure drawings and pole piece configurations.
Ground surface processing and thickness tolerance control support stable installation beneath humbucker screws, slugs, and blade pole assemblies.
Magnets can be supplied in magnetized or unmagnetized condition depending on pickup assembly sequence and production requirements.
Suitable for OEM guitar pickup manufacturing, custom hand-wound pickup projects, and batch production requiring consistent magnetic performance and dimensional compatibility.
What is an Alnico 8 guitar pickup bar magnet used for?
Alnico 8 bar magnets are installed beneath steel pole screws, slugs, or blade pole pieces in guitar and bass pickups. The magnet transfers magnetic flux through the pole structure toward the strings, allowing the pickup coil to generate electrical signal output from string vibration.
What is the difference between Alnico 8 and Alnico 5 pickup magnets?
Alnico 8 has higher coercivity and stronger magnetic pull than Alnico 5. In pickup assemblies, this produces a more concentrated magnetic field and increases output response, attack sensitivity, and midrange signal strength.
Which pickup types use Alnico 8 bar magnets?
Alnico 8 bar magnets are commonly used in humbuckers, high-output pickups, blade pickups, bass pickups, and custom hand-wound pickup assemblies requiring stronger magnetic field concentration.
Yes. Custom length, width, thickness, chamfer processing, and magnetization orientation can be produced according to pickup structure drawings and OEM production requirements.
