okay /sci/ I know you guys can help me out with this...

In the picture is a screw on the side of my chair, it has a hexagonal shaped bit for turning the screw.

You may be able to make out that one of my neodymium magnets has become lodged in the screw head.

Obviously because of the intense magnetism it really does not want to come out and because it's a sphere I can't really get a knife or anything under it.

How do I get it out? Without the 216th one the other 215 are useless.

a stronger magnet that will attract the other magnet's opposite pole and pull it out. i doubt many consumer magnets would be so strong that it would pull a screw out of it's threading.

you're fucked bro...the only thing I can think of is suction. But you'd need a lot of suction to get that off of their

I think your mom will do just the trick in that case.

Drill two slots in the head of the screw towards the magnet with a small drill bit. You should be able to remove the magnet from underneath, and then use a slot screwdriver to get the screw out.

ok, you got me guys. I lol'd.

I got another idea. Pliers to unscrew the bolt, grab the sides, it make take a little muscle. Then you're going to have to cut the bolt head with a wafer wheel. Just make sure to not cut the magnet. And be sure to wear proper eye protection, cause metal flakes in your eyes is bad news. Cut the bolt head off the bolt, then cut the back of the bolt head (where you just detached it from the bolt) to right up to the magnet, then make cuts on the top of the bolt until you connect with the cut on the back, also making sure to not hit the magnet. then put the bolt in a vice and begin pulling it apart.

If you can't find one, make one. Please tell me you can make an electromagnet. Please tell me I'm not the only /sci/co who keeps spare electronics in case I ever need to build something.

I consider insulated wire to be grouped with electronic supplies. A piece of metal? Maybe not. A regulated power supply? Definitely electronics.

Simply take a blowtorch to the magnet and the magnet is yours!!

There is no such thing as suction in physics, and there is no air behind the magnet so lowering the air pressure in front of it would have no effect.

The magnet it too strong for this.

You could try and get it to reach it's curie temperature, which I think for neodymium is something like 400 degrees C. Not sure it would still be magnetic afterwards though.
