Advancements towards renewable energy systems demand efficiency in production and storage to avoid potential waste. This investigation delves into understanding the behavior of magnets and their effectiveness in converting environmental vibrations to electrical energy. A program was written to predict the induction produced in a solenoid by a moving magnet in order to shed some light on how to treat magnets experimentally and theoretically. Various sets of solenoids ranging from six to four hundred windings were tested and their voltage outputs were compared. Considering that there is a gap of 28.1 mm between the magnet and the solenoids (not optimally placed), the device produced an AC signal of 130 mV amplitude with 60 windings and about 750 mV amplitude with 400 windings. Conclusions hint at designs of solenoids that will yield maximum power output from magnets at a fixed speed.
