Has anyone ever built a Light and Heavy box using the electromagnetic method?
What pitfalls did you encounter?
I'm curious as to how feasable this really is.
Thanks

Please let me know as well. thanks. or is the one that malloy sells anygood.

My frend has this kind of similiar magnet: http://www.noga.com/prdPics/DG0039_pic.jpg

Could this be used in the light&heavy box?

Barry Mitchell explains his electromagnetic version in his "Magic of thinking Creatively" DVD and his book. He also has a version that uses no magnets. (Which I use for my kid shows)

Check out the Light Heavy box at http://www.tomyurasitsproductions.com. If I were to get one, I would get his. There are several big names in magic that have his version. His box does not require any handling by the performer.

I went to Harbor freight tools and picked up a large suction cup, for pulling out dents, and mounted it inside a box I picked up from Michael's craft store. As long as the surface is smooth it can not be lifted. For an electronic version Barry Mitchell's book covers it pretty well.
