How To Remove A Magnet From A Steel Door

How to Separate Strong Magnets

Neodymium magnets are strong.  Really strong.  If y'all have never handled neodymium magnets before, you will be surprised at their remarkable forcefulness.  They're not the ceramic magnets you lot find at craft stores.

Whether talking about relatively small magnets similar one/4" bore D41 discs, or monstrously large cake magnets like our BX8X8X8, separating these magnets can show challenging to those without feel.

Hither, we share some of our strategies and tips for separating potent neodymium magnets.

The Basic Thought

Neodymium magnets pull towards each other with a strong strength.  If you try pulling two magnets directly apart, y'all demand quite a bit of force to pull them apart.  To carve up ane magnet from another, you'll demand to pull with a force equal to the listed Pull Forcefulness Case 1 number.

This tin exist difficult if the magnet is potent, or if there isn't much expanse to grab onto the magnet.  Almost methods of separating these magnets do ii things:

1. They provide more leverage and/or a ameliorate fashion to grip the magnets
2. They move the magnets autonomously laterally (sideways), which requires less force

Small-scale Magnets

Small magnets can be separated by mitt, usually without any mechanical aid.  Magnets with listed Pull Strength Instance 1 values of about 5 lb or less fall into this category.  The cardinal is to slide one magnet off the stack with a lateral motion, every bit shown in the video of D42 magnets beneath.

The video for our B333 cubes is also instructive.

If yous are having trouble, consider using the edge of a desk to help remove the summit magnet off a stack, as shown in the video beneath of our D63 disc magnets.

Medium-Sized Magnets

Medium sized magnets might range from ten to 50 lb in their listed pull force numbers.  While they tin can be separated by hand, information technology can help to use some kind of leverage such as the edge of a table.

The DX04 video below shows that information technology's easier to separate two magnets when a small plastic spacer is kept between them.  Once the spacer is removed, it is much more hard to separate by hand.  The video shows magnets separated using the edge of a desk and with our MAGS1 Magnet Splitter.

The RX038DCB-N52 is a stronger magnet, but we use the aforementioned techniques.

Exist conscientious treatment magnets in this strength range.  It tin exist easy to pinch your skin when treatment such magnets.  Also consider wearing safety glasses with magnets this size.  If immune to collide, small chips can fly off the magnets.

Big Magnets

We offering a number of really large magnets that are, quite frankly, challenging to handle.  Hither nosotros show our BX8X8X8 one.5" cube magnet beingness separated using our MAGS1 magnet splitter.  With a spacer between them nosotros tin carve up these magnets by hand, though I wouldn't recommend this without feel.

The method shown here using our magnet splitter is good didactics for magnets in the 1 to 2 inch size range.  We offer our MAGS1 magnet splitter for sale on our website.  For those who prefer to make their own, we fifty-fifty have an article posted about how to Build Your Own Magnet Separator Tool.

We take not notwithstanding posted videos for larger magnets.  For 3" magnets, we usually separate them with more than than one person involved to stay safety.  Be careful out in that location!

Alarm: Neodymium Magnets are Breakable and Fragile!

Neodymium magnets are made of a brittle material.  Don't let the shiny nickel plating fool you -- these magnets are non as stiff as steel.  They are more similar a brittle ceramic.  If you let two magnets slam together, they can crack and break.  This is true for magnets large and small.  Even modest D41 magnets can crack if yous let them fly together.

The video below includes some loftier speed photography showing what happens when strong magnets collide.
