   5 paź 2006 · I once had to recharge the magnets in an antique TV's CRT focus assembly. They appeared to be alnico magnets.

   11 sie 2014 · Some AlNiCo magnets do degrade with time, others not so much. It seems to depend on the specific formulation type, shape, and whether "naked" or part of a closed field assembly or the field closed with a "keeper" when otherwise naked. Also some alloys seem to respond to charging easier than others.

   Magnet recharging centers. Since Alnico magnets loose 50% of their charge in 100yrs, It would be very helpful to compile a list of speaker repair centers that are capable of bringing these tired relics back to their optimal performance levels.
