GUITAR PICKUP MAGNETS

GUITAR PICKUP MAGNETS - AlNiCo & Ferrite The magnetic pickup mounted on the Electric guitar's body help the sound production. A vibrating string cuts through the magnetic field in the pickup to produce a signal in the pickup's coil. What the magnets in pickup look like: Two type permanent magnets are used in pickups: AlNiCo [...]

Magnet Materials

Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]

History of Permanent Magnets

History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]

What is Speaker Magnet

What is Speaker Magnet The neodymium speaker magnet produces a magnetic field, and the speaker’s voice coil motor is placed in the magnetic field. When the voice coil passes through the audio current, the current will be acted by the magnetic field, which causes the voice coil to vibrate, and drives the paper basin that [...]

High Temperature Resistance Magnets

High Temperature Resistance Magnets Not all magnets are suitable for use in really high-temperatures, while some grades excel. Many applications, particularly within the manufacturing and engineering industries require magnets to be able to maintain their performance at incredibly high temperatures. Here you will find a selection of ferrite, alnico, samarium cobalt and special high-temperature neodymium [...]

Three environmental factors affect function of high temperature resistant magnet

Three environmental factors affect function of high temperature resistant magnet Environment temperature. Since sintered NdFeB has a negative temperature coefficient (αBr<-0.13%/°C, αHcj<-0.6%/°C), the instantaneous maximum temperature and the continued maximum temperature of the operating environment will cause different degrees of demagnetization of the magnet itself. Contains reversible and irreversible, rehabilitative and non-recoverable. Environment humidity. NdFeB [...]

What are the difficulties when cutting ferrite magnets?

What are the difficulties when cutting ferrite magnets? A ferrite magnet is a metal oxide having ferromagnetism. In terms of electrical characteristics, ferrite magnets have much higher electrical resistivity than metal and alloy magnetic materials, and also have higher dielectric functions. The magnetic function of the ferrite magnet also exhibits a high magnetic permeability at [...]
