There are a few ways to destroy a magnet. By impact Rough handling (dropping, hitting, etc.) a magnetized item can weaken it as well as creating one from iron bearing metal. That's how tools become magnetized in the first place. (Isn't that ironic?) Chances are that all of the handling was random so undoing it must not be random to be most efficient. You'll ...

Waterproofing (rust-proofing) magnets is a common application in aquarium environments where you want to attach various fixtures to a glass/acrylic fish tank with a pair of magnets. You can actually purchase coated magnets that are meant for wet environments, but I'll stick to common DIY techniques that can make a magnet waterproof at home. Waterproof Epoxy ...

Paint the magnet with a good enamel paint. Ensure that the whole magnet is completely covered. You may need to apply multiple coats of paint. Follow the manufacturer's instructions on how to apply the paint. Depending on how the magnet is coated already, you may need to apply a coat (or more) of primer so that the enamel paint will adhere properly for a ...

It is impossible to cut a speaker magnet with a hacksaw because the magnet material is harder than the hacksaw teeth. You can break a magnet into smaller pieces by scribing the break lines onto the magnet surface with a single point diamond scribe and then flipping the magnet over and striking the backside of the magnet surface with a hammer and chisel, ...

It looks as though the magnet is stuck to a raised black metal piece, and "above" it is non-magnetic wood. My solution is to slide one end of the magnet "up", so it sticks out over the wood area. Once that tip is sticking out, you should be able to grab it with your fingers (or pliers) and lift it off the metal. It will be even easier if you can prevent the ...

Try magnets modified for your specific requirement. There are two immediate possibilities. - Rubberised neodymium magnets Rubberised magnets are completely coated by a plastic layer. That makes them perfectly suitable for longterm use outdoors, in wet surroundings or even under water (e.g. in aquariums).Their finish doesn't scratch surfaces as a normal ...

Try sticking one or two fine bladed screwdrivers down the side of the key sufficiently that you can turn them and operate the lock. Dont force it! If it wont turn easily it would be better to try sticking a third screwdriver sideways between the stems of the two driver and rotating it With the door open you should be able to remove the lock barrel, push the ...

These are typically "ferrites". Not metals but intermetallics. So they are not malleable /deformable like metal. Think of it as having physical properties like a ceramic- hard, brittle. It may be cuttable with an abrasive wheel but you may need a diamond wheel as would be used for ceramics,

Lots of options here, mostly not lifehacks use a large safety pin (diaper pin) to pin the ribbon to the baby's clothes (yes, this leaves small holes in them, that's why most people use the clips) use a pacifier bib clip the clipper somewhere the baby can't reach it such as on the shoulder blade; this increases the chance the baby can't reach the pacifier ...

Use a c clamp and tighten it around the magnet. Now you have good grip you can pull the clamp with great force finally take apart the magnet

There are several videos on video sharing sites showing solutions for this problem. The easiest solution is to take some plastic object (stick-shaped is best, a glue-gun stick is shown in the videos). Using some heat (lit match, lighter, candle...) melt one end of the plastic stick. Attach the melted plastic to the key inside the safe - try to NOT attach ...

I was able to demagnetize the vise grips by heating it up for about 5 minutes using a propane torch.

Beyond the great answer by Stan, there are actually a few tools that'll demagnetize things. Googling "demagnetizer" seemed to bring up a lot of good options, with a lot of places to get them, including the standard online, department, and home improvement stores. You can demagnetize the tips of the jaws, but not the whole tool with this one. You rub the ...

Hot melt adhesive is pretty waterproof and if you have it available I would carefully paint the magnet with the hot melt. You can re-flow the glue with a hair dryer or gas lighter to smooth the surface if you are very careful not to get stuck to the molten glue. A quick fix might be to put petroleum Jelly/Vaseline/Silicone grease into the bag with the ...
