Magnet separator for strong magnets
Separating magnets the safe wayWe often get the question: "How do you properly separate large neodymium magnets?" Because when two very strong magnets connect, it is extremely difficult to pull them apart again.
One of several solutions is to build a wooden magnet separator. With this contraption, you can easily and safely separate magnets.
The PDF contains a list of all the materials you need along with step-by-step instructions, drawings, and exact measurements.
Materials neededTo build a magnet separator you need different boards, hardware, and tools. The downloadable PDF includes a shopping list and detailed instructions.
The following two articles needed for this construction are available from our online shop:
Step 1Cut the wooden boards with a jigsaw (or alternatively with another saw) according to the PDF manual.
The result is nine individual parts (A1, A2, B1, B2, C, E, F1, F2 and G), from which the magnet separator will be assembled.
Step 3Now the two "A" parts are screwed together at the marked places. For that purpose screw the 7 countersunk wood bolts through "A2" into "A1". The resulting part will now be called"A1-A2".
Tip: In order for the screwed-together parts to have a good footing, it is important that they are flush especially at the bottom edge.
Please note: If you don't have counterunk bolts avaialble, the wood should be predrilled prior to screwing in the screws so the screw heads may be sunk in.
Step 4In this step the marked hole for the M8 hexagon bolt "J" (with which the lever arm will be fastened later) is screwed into the parts "A1-A2" and "E".
The edges of all parts are sanded down as necessary to make them smooth and avoid splinters later.
Step 5The part "F1" is now screwed into the cavity of "A1-A2" with two small countersunk wood bolts "I" as marked in the manual. This ensures that the magnet will rest as flat as possible.
Tip: If the surface has become a little uneven from the sawing, this can be remedied with sanding paper.
The two feet "B1" and "B2" are now screwed together with 4 medium countersunk wood bolts "H" at the marked places on the part "A1-A2". The resulting combination is now called "Body".
Step 6Then the part "E" is screwed together with the strenghtening "C" – 3 medium countersunk wood bolts "H" are used for that. The resulting combination is now called "C-E".
Step 7The part "F2" is screwed onto the bottom side of "C-E", which results in the complete lever arm (called "Arm" in the manual).
Step 9On the top side of the base plate "G" a thin soft sponge "O" is attached. In our case, we used UHU MAX REPAIR "N" to glue it to the spot where the separated magnet will drop later. This way the magnet will not be damaged or pulled underneath the Body.
On the bottom side of the base plate "G" we glue 3–4 pieces self-adhesive metal tape 35 mm "M", which will "catch" and attract falling magnets. Since it is a thin metal tape, even strong magnets can be easily removed.
Separating magnetsThe magnet separator works especially well for large and strong neodymium magnets – we listed some of them below. Tips for separating smaller magnets are outlined on our FAQ page.
