High Temperature Custom shape Magnets alnico magnets for guitar pickup
It's not really necessary for a pickup to have a magnet at all, but it helps. The magnet acts as the juice for the signal flow. The shape and type of magnet used in each EMG Pickup is different. Ceramic magnets don't affect the inductance of the coil but have a much stronger magnetic field. Alnico material exhibits less magnetism yet greatly increases the inductance of the EMG design. Each has an affect on the resultant output and frequency response of the pickup. The addition of steel poles (either bar or screw/stud) increase the inductance of the pickup design and further change the results
