Rerurn to Romy the Cat's Site

Hi.

1)  He was very certain that it was not a result of a softening of the suspension or the speech coil for that matter.
2)  Probably it it is more significant to look at the harmonic structure and decay of the vibrational spectrum of the magnet when excited.
3)  It was definetly not a matter of weakening of the field, the temperatures used where way to low to have any effect on this.
4)  He has not pursued electromagnets since they have sonic ill effects as well and the small advantage of grain freeness over permanent magnets can be elliminated with the said heating anyway.
"He" is Filip Keller / AER
5)  Probably
6)  I am shure of that, you could just mount a power resistor on transformer core and put some current in it.
