Speaker magnets


Three questions:
1) The coil in a speaker when fed with current from the amplifier will produce its own magnetic field, presumably 4 layer coils more so. Over time does this ever have any effect on the characteristics of the speaker magnet?
2) Modern speakers have massive magnets compared with most vintage speakers. What advantage do they give a modern speaker over a vintage speaker?
3) Does the magnet in a speaker deteriorate to any noticeable amount just due to age?

Plus 1 on weirdness and magnets. Can be very creep and/or surreal. Normal stuff like a fire truck using its flashing lights (no sound) and coming up the mountain road right by you, seems like a religious experience. But at least you realize why it’s happening (well placed warning signs that recommend limited exposure times).
