How To Get Two Magnets Apart
How to Split up Stiff Magnets 
Neodymium magnets are strong. Really strong. If you have never handled neodymium magnets earlier, you will be surprised at their remarkable strength. They're not the ceramic magnets you find at arts and crafts stores.
Whether talking about relatively small magnets like 1/4" diameter D41 discs, or monstrously big block magnets similar our BX8X8X8, separating these magnets can prove challenging to those without experience.
Hither, nosotros share some of our strategies and tips for separating strong neodymium magnets.
The Basic Thought
Neodymium magnets pull towards each other with a strong strength. If yous try pulling two magnets direct apart, y'all demand quite a bit of force to pull them apart. To separate 1 magnet from another, yous'll demand to pull with a force equal to the listed Pull Force Case 1 number.
This tin be difficult if the magnet is stiff, or if there isn't much area to grab onto the magnet. Most methods of separating these magnets do two things:
- They provide more leverage and/or a better way to grip the magnets
- They move the magnets apart laterally (sideways), which requires less strength
Small-scale Magnets
Small magnets tin exist separated by manus, normally without any mechanical aid. Magnets with listed Pull Force Case 1 values of almost 5 lb or less fall into this category. The primal is to slide ane magnet off the stack with a lateral motion, equally shown in the video of D42 magnets below.
The video for our B333 cubes is also instructive.
If y'all are having trouble, consider using the edge of a desk to assistance remove the top magnet off a stack, equally shown in the video below of our D63 disc magnets.
Medium-Sized Magnets
Medium sized magnets might range from 10 to 50 lb in their listed pull forcefulness numbers. While they can exist separated by manus, information technology can help to employ some kind of leverage such equally the edge of a table.
The DX04 video beneath shows that it's easier to carve up two magnets when a small plastic spacer is kept between them. Once the spacer is removed, it is much more difficult to separate past mitt. The video shows magnets separated using the edge of a desk-bound and with our MAGS1 Magnet Splitter.
The RX038DCB-N52 is a stronger magnet, but we utilise the same techniques.
Be careful handling magnets in this strength range. It can be easy to compression your peel when handling such magnets. As well consider wearing safety glasses with magnets this size. If allowed to collide, small fries tin wing off the magnets.
Large Magnets
We offer a number of really big magnets that are, quite bluntly, challenging to handle. Here we show our BX8X8X8 1.v" cube magnet existence separated using our MAGS1 magnet splitter. With a spacer between them we can carve up these magnets by mitt, though I wouldn't recommend this without experience.
The method shown here using our magnet splitter is skilful instruction for magnets in the 1 to 2 inch size range. We offering our MAGS1 magnet splitter for sale on our website. For those who prefer to make their own, we even take an article posted most how to Build Your Ain Magnet Separator Tool.
We have not still posted videos for larger magnets. For 3" magnets, we usually separate them with more than one person involved to stay safe. Exist careful out there!
Alert: Neodymium Magnets are Brittle and Delicate!
Neodymium magnets are made of a brittle textile. Don't let the shiny nickel plating fool yous -- these magnets are not equally strong as steel. They are more like a breakable ceramic. If you let two magnets slam together, they can crack and break. This is true for magnets large and minor. Even small-scale D41 magnets tin can crack if yous let them fly together.
The video beneath includes some high speed photography showing what happens when strong magnets collide.
