What would magnet keepers look like for use in conserving the field strength of four curved rectangular magnets fastened within the inner circumference of a rotor (flywheel) of a simple AC Generator (+, -, +, -)?
This AC generator powers the ignition system of a mid-late 70's, Japanese-manufactured small displacement motorcycle engine. The rotor of this generator needs to be removed to facilitate repairs to the engine. The goal is to preserve the field strength of the rotor's magnets while the rotor is uninstalled.
