I had a brainstorm this morning. I want to make a jewerly box for my 4 year old granddaughter, but I want it to be a little "magical". To that end I want to use a steel ball in a track sandwiched between two thin sheets, the steel ball would be held at one end by a low power magnet and moved to the other end by a "magic wand" (stick with a magnet on the end"" where the steel ball would activate a magnetic catch, allowing the lid to open.
Does anyone know where I can find low power magnets and low power magnetic catches. Or suppliers that list the power of the magnets involved. If I know how strong the catch magnet is I can get a strong rare earth magnet to put in the wand.
Thanks in advance.
