Magnets do not 'leak' or 'weaken over time', they need an outside influence to weaken them. Stored too hot (above 250 °C) or too cold (below -40 °C) will weaken a ferrite magnet quickly, getting near those temperatures will slowly weaken them slightly. Mechanical shock like striking with a hammer will quickly weaken a magnet, or storing a ferrite magnet near a stronger magnetic field can weaken or even could reverse the polarity.

Just wondering how you determined the magnets were weak and not the coils having internal shorts from insulation breakdown in the magnet wire.
