Abstract
A method of making blocks with internally disposed magnets. Pockets for the magnets are machined into a non-extrudable material such as wood. Strong permanent magnets are disposed in the pockets to cause the faces of the block to exhibit a desired polarity magnetic field. The pockets are then sealed to permanently retain the magnets. The exterior shape of the block may be formed either prior to or subsequent to machining and sealing of the pockets.
Claims16
A method comprising:
- forming a pocket to be adjacent to a center of each face of a plurality of faces of a defined geometric solid of a non-extrudable material;
- inserting a permanent magnet into each pocket such that a number of faces exhibiting a north polarity is equal to a number of faces exhibiting a south polarity;
- and
- sealing the pockets to permanently retain the permanent magnets.
1 more element
A method comprising:
- defining a desired ultimate geometric shape;
- forming at least one pocket portion in a first piece of non-extrudable material the pocket to be internally proximate to an external face of the ultimate geometric shape;
- forming at least one pocket portion in a second piece of non-extrudable material to be internally proximate to an external face of the ultimate geometric shape;
- disposing a permanent magnet in each pocket;
- and
- coupling the first piece of material to the second piece of material.
