Encasing a neodymium magnet in plastic?
Encasing a neodymium magnet in plastic?
(OP)
Has anyone done this? I'd like to have two 4x4 plastic pieces that are 1/2" thick be able to attract and pull apart. I read that doing this will reduce the pull force by approximately 45%. I'm also wondering how to do this as I've never worked with plastics. Maybe use a router to create a cavity and seal it somehow? Or perhaps make a mold and pour plastic on the magnet? Perhaps that is a question for another forum but I appreciate any thoughts.

The thinner the better for magnetic strength. So at least the faces that attract each other need to be very thin.

By the way, if you have 4x4'' cylindrical magnets with a residual flux of 12,500Gs, a distance of 1/2'' is about to decrease pull force to 55%. But if the size is only 1x1, a distacne of 1/2'' would decrease pull force to only 7 to 8%!

Alternately, get weaker magnets and coat with: http://www.homedepot.com/webapp/wcs/stores/servlet...
