   Note that the "don't find meteorites with a magnet" advice doesn't really apply to amateurs hunting micrometeorites in rooftop dust. There are so common, and so small, that you're not going to destroy any research-worthy magnetic fields. (Although if you can come up with an efficient non-magnet method for that, I'd like to hear it. I've had some success in a "gold panning" style to filter out all the lightweight stuff before using a magnet.)
