Magnet that are pressed into the Vulcanized Fibre flatwork should not be move or adjusted. The beginning of the coil and magnet wire are wound directly around the rod magnets that are pressed into the flatwork. If you try to move the pole pieces for better string balance you can permanently damage the coil from…

You can use rod magnets in place of the studs and make sure the correct polarity is proper on the stud side of the humbucker. The stud polarity should be opposite from the adjustable side which is normally South polarity. You should have all the North polarity rod magnets facing up. The pickup will probably…

You can flip the magnet over 180 degrees to change the magnetic polarity of the pickup and you can adapt magnets of different materials such as Ceramics, Alnico 5, Alnico 4 and different dimensions to your needs. If you use different magnets, make sure you secure or have the pickup potted to eliminate unwanted feed…

Magnets manufactured today may have closer tolerances than products made 40 or 50 years ago. Over time the magnet can be altered by age, heat, shock or other outside electrical elements such as transformers or other magnets. Companies try to keep tight tolerances when being manufactured but some are not always kept. When I say…

A pickup actually uses the strings as a keeper with an air-gap in between the poles. A keeper is usually used on a horseshoe magnet to complete the magnetic circuit. A keeper is not a working part of a magnetic circuit but it keeps the circuit stabilized when not being used for any specific purpose….

Calibration of a magnet is to reduce the level of magnetization to a predetermined or custom strength of a particular magnet. Alnico magnets are my favorite to calibrate and I can control the amount of magnetic field to the strings. I feel you don’t need all the magnetic field you get from certain Alnico magnets…

Early magnetic investigators attempted to describe the magnetic fields present in magnets. The invisible force field or magnetic field that travels through the air and when moved through a coil produces or generates a alternating current. The field travels from North to South through a magnetic circuit.

An isotropic magnetic field is a magnetic field where the properties are the same in all directions. Rod magnets are normally magnetized with one end North and the other South and have an anisotropic magnetic field. Bar magnets can be made to be isotropic and can be magnetized in several directions.

A material that is attracted to a magnetic field such as a guitar string made of spring steel and wrapped with a desired outer wrapping. The vibrating ferrous string disturbs the magnetic field and induces a current in the pickup that is sent to the amplifier through a variety of controls to blend, enhance the…

An Alnico magnet is made from various element combinations for different grades of Alnico. Alnico magnets were developed by G.B. Jonas in 1939 and his patent for Alnico’s is 2,295,082. Cast Alnico is a combination of Aluminum, Nickel, Cobalt, and Iron as a filler. There are around 12 grades of Alnico with both Isotropic and…
