Inquiry (采购产品): Very Strong Magnet I had an extra Large Alnico Magnet. Out of a WWII feild phone. It Measured 7.5" * 5.5" *2.5". It was extremely strong and I use it for many different physics expirements. One of my students broke it in half, and I need to replace it. It's average field strength was over 4000 gauss. It would be a horseshoe shape with a 1.5" opening at the end. **** Hidden Message ***** James Nicolas 49404 Company: Coopersville High School E-mail: jnicolas@coopersville.k12.mi.us **** Hidden Message ***** jnicolas@coopersville.k12.mi.us
