Use wire wrapped around a permanent magnet to generate an electrical field in response to the vibration of a metal string. Magnetic pickups have a number of factors that effect the quality of sound generated by them. \\ | Use wire wrapped around a permanent magnet to generate an electrical field in response to the vibration of a metal string.

The degree of intensity (Gauss) of a magnet greatly effects the kind of sound output the pickup will generate and the stronger the Gauss the more variety of frequencies that will be picked up by the magnet. Weaker magnets generally preference low frequencies over higher ones. The vast majority of pickups use alnico or ferrite magnets. Both of these magnets can be selectively magnetized using strong magnets to the desired Gauss.

There are many methods for wrapping the wire, with the primary methods being to uniformly wind the wire and to do something called scatter winding.

- | For good ability for an amplifier to pick up a signal about 7500 rotations of copper wire are needed. Generally speaking the commercial amount of rotations recommended is 10,000 rotations for bridge pickups and 9000 rotations for neck pickups. Resistance at 7500 rotations is about 7.5k ohms and at 10000 rotations is 8.5k ohms.

After the pickup has been constructed the layers of copper wire and magnets need to be completely encased in a neutral material to prevent any kind of motion of the wires. This is generally doing by submerging them in hot paraffin wax of shellac. In many cases they are also placed under vacuum pressure to remove any air that remains. | After the pickup has been constructed the layers of copper wire and magnets need to be completely encased in a neutral material to prevent any kind of motion of the wires.

A clavinet pickup made custom by a pickup maker, note the unusually long magnets and winding of the copper wire, this is proof of concept for the idea that though guitar pickups use only about 4 inch wide coil loops, a far longer loops can be made, perhaps even ones that are feet long.
