Hi all
I've been trying to make my own dent eraser for some time now, but I don't really know how strong the magnet should be. My second magnet has been rated to lift 70 kg but it's not enough. I use some dent balls made from steel. The largest dent ball is 3.5 cm in diameter. So I wonder is the magnet too weak or am I using the wrong dent balls? Any input will be appreciated.
Thanks for reading
