hey everyone i just recently modified an old vivitar 2000 flash to create a magnetic pulser. i created a coil by using an air core inductor and wiring 2 leads to it. I removed one wire off one end of the flash tube and then wired one of the leads from the coil to the flash tube. the other lead i wired to the single wire i removed from the flash tube. it was working for about a week before the flash tube blew up. I need to redesign this thing so that it creates a stronger magnetic pulse, when i tested it at school it onyl read 122 gauss, if thats what 122 on the gause meter meant. anyways any ideas on what to replace the flash with to get between 20,000 and 40,000 gauss?
