How To Remove A Strong Magnet From Metal

Instead of trying to pull them apart, firmly slide and/or twist them abroad from each other and far enough apart so that they don't bound dorsum together.

Neodymium magnets are exceptionally strong. If you've never handled them earlier, you will probably exist surprised past how powerful these magnets can exist.

This is because neodymium magnets are the strongest type of permanent magnet commercially available. In fact, they are far stronger than all other ceramic or alnico magnets of equal size – with a magnetic energy value as much as 18 times greater than these other magnets by volume and 12 times greater past mass.

Helpful Tips

The primal concept in a nutshell: Neodymium magnets pull towards each other with a strong force, more double the pull force rating of each magnet.

As a result, if you endeavour to pull 1 magnet off a stack or two magnets straight autonomously y'all will need at to the lowest degree double the pull force to separate them as well equally a greater amount of leverage than the magnet's actual size allows. This challenge becomes even more pronounced with medium and big magnets.

So the virtually efficient manner to separate magnets is to devise a method to get more leverage or a better way to grip the magnets and to provide enough force to move the magnets laterally or sideways, which requires far less forcefulness or strength than trying to pull them direct autonomously.

How to Separate Pocket-size Magnets (0 - 5 pounds of pull forcefulness)
Minor magnets tin can normally be separated past hand, usually without much effort or mechanical assistance. Magnets with listed pull strength ratings of up to five pounds can be slid apart without much resistance. The key is to slide i or more magnets off the stack with a lateral move, as shown in the diagram above.

How to Separate Medium Magnets (6 - 11 pounds of pull force)
While many medium-sized magnets tin be separated by hand, information technology can be helpful to use some kind of leverage such as a vise or the border of a workbench or table with the stronger ones.

Also, many medium-sized magnets come with modest plastic washers or spacers between them. This is because information technology's far easier to split up two magnets when a spacer is kept between them. In one case the spacer is removed, information technology is much more difficult to carve up the magnets by hand.

Exist extremely careful with magnets in this size and strength range. While they may appear pocket-size and relatively harmless, they can easily snap back together forcefully and compression your peel and even depict blood.

You may also desire to consider wearing work gloves and safety spectacles when handling magnets of this size. If non handled properly, they tin slam together with such forcefulness that small-scale chips of the nickel coating can wing into the air.

How to Carve up Large Magnets (12 – 25+ pounds of pull strength)
Some larger magnets with spacers can be separated by highly-experienced and strong hands. In virtually cases notwithstanding, added leverage is needed – such every bit using the edge of a workbench or table, a vise or a magnet splitter.

You volition also want to exist extremely conscientious with magnets in this size and strength range. While they may withal appear modest and relatively harmless, they volition jump back together more rapidly and forcefully than small or medium-sized magnets.

Exist sure to get them far apart once yous have separated them.

You may also desire to consider wearing work gloves and safe glasses and working with another experienced person when handling magnets of this size.
