Magnetic power generation

An apparatus comprising:

• a batteryless electronic circuit;
• a chamber;
• a first permanent magnet configured in the chamber;
• a second permanent magnet external to the chamber and moveable relative to the first permanent magnet at a distal end of the chamber, the first and second permanent magnets configured to generate a first magnetic force that changes in response to the movement of the second permanent magnet relative to the first permanent magnet;
• a magnetically susceptible element external to the chamber and located at the proximate end of the chamber, the magnetically susceptible element and the first permanent magnet configured to generate a second magnetic force that changes in response to the movement of the first permanent magnet relative to the magnetically susceptible element;
• and
• an inductive coil magnetically coupled to the magnetically susceptible element, the inductive element having an output coupled to a power input of the electronic circuit,
• wherein when the first magnetic force is greater than the second magnetic force, the first permanent magnet is pulled toward the second permanent magnet and away from the magnetically susceptible element,
• wherein when the second magnetic force is greater than the first magnetic force, the first permanent magnet is pulled toward the magnetically susceptible element, and
• wherein movement of the first permanent magnet causes a change in a magnetic flux of the magnetically susceptible element, and in accordance therewith, produces a voltage at the output of the inductive coil to power the electronic circuit.
