Abstract
An automatic tuning system for pendulum clocks provides for a separable magnet and ferromagnetic attractor, one positioned on the pendulum and one positioned off of the pendulum and adjustable to change the separation between the two. The magnetic attraction between these elements serves to simulate a changing gravitational force fundamentally affecting pendulum period.
