Thanks for the bismuth locations to buy but it's complelty useless now ...I've done one experiements with a 1.5 feet diameter, 2 inch thick plate on the spot at the laval university where it lies on a shelf in a class and about any magnet passed through as if it wasn't there. Brief it barely modify the field itseft to be noticable. So using bismuth as a magnetic field reflector is completly useless. But thanks for taking the time to respond it's always appreciated.
