Custom Magnetic Jigsaw Puzzles | Custom Magnetized Puzzles
Calculating the number of magnets needed in your custom magnetized puzzle.
Each embedded magnet in each puzzle piece give the appropriate gripping power for TWO to NINE square inches of area.
The math is simple. To calculate the "average area" of each piece in your puzzle, simply do the following.
1) Multiply the height x the width of your puzzle to calculate the total puzzle area. Example: 20" x 30" = 600 square inches of area
2) Divide the total area by the piece count that you want your puzzle to be...
600 / 100 pieces = 6 square inches of average area. Only 1 magnet per piece will be needed. (See the chart at the top of this page)
600/ 30 piece puzzle = 20 square inches of average area per puzzle piece. 3 magnets are needed to give these larger magnetic jigsaw puzzles the appropriate grip.
3) Round custom puzzles are calculated by the simple formula...
Pie (3.14) x Radius Squared = Area
A 24" diameter circular magnetic jigsaw puzzle is calculated as follows...
3.14 x 12 x 12 = 452 square inches of total jigsaw puzzle area.
How my magnetic wooden jigsaw puzzles work...
I custom make magnetic jigsaw puzzles with as few as 6 pieces to as many as 2,500 pieces. Magnetic puzzle pieces are fantastically strong. These magnetized puzzles will have no trouble clinging to any magnetic receptive metallic surface that is flat.
Magnetic Dry Erase Boards are most commonly used to display and work these magnetic wooden jigsaw puzzles.
