Separating large neodymium magnets

This is another video in my series of videos on how to handle large neodymium magnets safely.

In this video I show you how to separate two large neodymium magnets without destroying yourself or the magnets.

The tool is not my invention but I did make it myself out of scrap wood. Other examples of this tool you can find on robgallagher and kjmagnetics channels here on Youtube.
The combining procedure is my own trick.

Hello! In an earlier video I showed you how to safely put together two large neodymium magnets. In this video I'm going to take them apart again.

For this job you need a splitter tool like the one shown here. This is not rocket science or fine craftsmanship - it just gets the job done. I call mine the BS Tool... which of course stands for big splitter tool...

Here's how it works. Place the combined magnets in the cutout making sure that only one magnet sticks out - just like shown.

Before I start chopping I prefer to put a sponge on the landing zone. This cushions the blow and makes it easier to remove the magnet again.

Let's chop! Because of the spacer and the big size of the tool this doesn't take much effort at all considering the power of these magnets.

At some point the magnetic fields of the two magnets will start colliding. The loose magnet will however solve this by itself as you can see.

Now remove the upper magnet straight away from the lower magnet and place it far away. The lower magnet will drop on the sponge and hang on to the metal plate on the bottom of the splitter tool. Here you catch a glimpse of the real power hiding in these magnets.

Remove the second magnet and now you will have two loose magnets. Job's done and no one got hurt. Perfect!

Before storage I will combine the two magnets again. For a complete and safe description of this proces watch my previous video on how to combine magnets.

have u lose a finger so far?

@yyhaoyue:

Thank you for your concern but no :)

I saw the video where a guy lost a nail and fingertip with neodymium magnets before I bought a big magnet myself. I'm fully aware of the risks.

Did you make that separating tool?

[brainiac75]

@mrmagnetsarecool:

Yes. I made it from scrap wood from a furniture factory. Hard wood is optimum for endurance but it could be made with softer and cheaper woods.

I didn't bother to sand it for a nice finish but it works :)

At about what is the maximum temperature magnets from magnetportal can withstand?

[brainiac75]

,@Walkingdeadman1991 :

'Normal' neodymium magnets like the ones from magnetportal shouldn't be used above 80°C (176°F). You can buy special neodymium magnets for higher temperature applications. They can be recognized by extra letter behind the grade - like N45M or N45SH. The highest I have seen is N33AH which can withstand 220°C (428°F) but it is only strength grade N33 (probably due to a lot of additives that ensure high temperature resistance but thins the neodymium-iron-boron composition).

@brainiac75 Yes, please make a video showing that!

@MrBurnTec lol

[fatelook]

I love your videos! TY for making them!!

[SeanACampbell]

@MrBurnTec Hahahaha like a boss.

[MrBurnTec]

@SeanACampbell duck and cover

[SeanACampbell]

@MrBurnTec That sounds dangerous lol

@brainiac75 Looks great, I recently built one out of hard wood designed to handle large magnets. I kept your design in mind during construction. I have seen other splitter tools on YouTube that look insufficient to fully protect you and don't seem to take into account the fact that the magnet will flip to correct itself when the magnetic fields collide. These large magnets are no joke, no point in taking unnecessary risks.
