Hi List, I have wondered if the magnetic holders are a good idea or not. I don't like or permit people to put magnets on my for sale specimens because some researchers do magnetic field tests on specimens (these are very very mild fields that show orientation of the specimen). I don't know of all the scientific value of these magnetic field tests but placing a powerful magnet on any meteorite would ruin the specimen for this type of test. I am not putting the sellers of these holders down (pretty innovative) but specimens should be kept in their natural states without any sort of outside influences if they are to be studied in the future. All my best.
