While reading through various shop solutions I've come across quite a few magnetic solutions for this and that. Problem is I've always had an anti-magnetic phobia about having the nasty things anywhere near my tools or instruments. For certain I would never intentionally bring them anywhere near a magnet.

Is it just me? :D

Assuming you and I are the only two people, then yes, it's just you. :)

Seriously, I don't recall ever having ANY problem at all with magnets. I view them as my friends. (I guess I don't have many friends these days, ...sniff, sniff)

Hi,

It ain't just you. I tend to have a dislike for magnetic chip holding finger slicers myself.

So far we got them out numbered 2:1.:D

Not exactly answering your questions, but for my big/strong magnets I keep them in a ziplock bag.

Any attracted chips are on the outside of the bag, simply turn the bag inside out and no mess to clean up. ;)

Blow gun and a trash can is one,if the mgnet is stuck in it's holder really good a wack on the rim of the trash can knocks most of it off.

A sharp impact on magnets can effect their magnetism.

Compressed air works well, and if there are stubborn filings on there- some strips of duct tape will remove all the remaining leftovers. Sort of like one of those adhesive roller lint brushes.

I use those rare earth magnets pretty much everyday, for all kinds of things. Sure, the occasional screwdriver, file or other small tool gets annoying when it attracts chips but that's why I have a cheap-o demagnetizer on the bench.

I have a small selection of articles on a few of the ways I use magnets listed near the top of this page:

One of the most handy things in my shop is the dusting brush, which I can stick pretty much anywhere, thanks to its handle magnet:

They're only nasty if you aren't wearing the proper hat.
Tinfoil works well.
Keep those things away from your brain man. :eek:

I brush my magnets very violently with a brass brush and it seems to fling the debrie off.

It's good to have company but it would appear that we are greatly outnumbered. No matter though, cause I'm too damn old to change my ways. There's no fun like chips clinging to cutters or drill bits re-cutting the same damn metal over and over again! They can keep their magnets. :p

Speaking of magnets, which I am, one of my most useful tools is a big round magnet attached to a long wooden broom handle , from Tractor Supply ( and probably a lot of other places.) I just used it today to fish a nutdriver out of a water filled sump , and I use it now and then to find parts I've dropped into the grass. Sure, if I was less clumsy I wouldn't need it so often , but the years take their toll. This thread also reminds me of another poster who observed that small tools in a shop tend to become magnetized , somewhat by themselves. I observed the same thing, except for tools that are supposed to be magnetized, which tend to lose their magnetizism. Apparently, there's only so much to go around, or something.

Hi Chris,

I'll side with you.:) Magnets are great tools , but I prefer not to have any other than my mag base. Chips stuck to vises ,parallels and cutters not good.
An edge finder that gets magnetized over time can get you in trouble,also.

Yup, HF sells a 25lb pull magnet on a 36" extension, very handy for $7.

I think the tractor supply one is more powerful magnet, but double the price too....

I have an old HF horn driver magnet (from the trash at the old work) on a rope for clearing nails from the yard after the roofers have been, and the like.

Drag it around in the tall stuff, and listen for the 'klink-klink" of nails hitting it.... clean off after a few and continue.

Elsewhere, every ^%$#@! thing in the shop seems to get magnetic..... I need to wrap a big coil around the place and wipe it like a ship. I don't bring any more of the evil things into the shop than I have to.

I put a magnet ground clamp on the botton of my 4 legged cane after the 1/2" bit came out of the drill & fell into a 55 gal drum. It's amazing how handy & what I find at the end of the day.:D

I do not purposely stick any tool to a magnet. I'm not fond of finding stuff stuck to a wrench or whatever, nor of the tool sticking to something. Many times I find that a drill bit will have become magnetized after drilling a hole- it's annoying.

Magnets are fun and useful though. I must have 50 or more stuck to my fridge, and I've got a wad of metal parts on one shelf that has a collection of magnets inside it somewhere-

Got a laugh the other day- I was paying for some nuts and bolts and gave the girl a bill and some change. She accidentally dropped one of the coins into the printer. Well, she can't finish the transaction that way since the printer might eat the coin and be damaged. I hand her my key ring- 'what, you want me to throw these in there too?' No, just use the magnet, maybe it will pick up the coin. Sure came in handy that day.

I have that magnet on my keychain mainly because I read somewhere that copper wire from China was magnetic. I had to test this idea, since I know that copper isn't magnetic, so now every time I see copper wire in some store, I whip out the magnet and test it. Couple of times now I've taken a roll of wire up to the front counter and said 'this wire is defective'. The counter person will say no it isn't and then I show the magnet being attracted to it. Gives me a laugh anyway, not the store owner-

I have never been injured by a magnet. Plain old pliers, on the other hand, have been responsible for several blood blisters. Ouch!

Magnets are like any tool, use with care.

Even if you never use magnets, tools often end up magnetised.

The answer is to have a degausser!

And if you don't have a real degausser, pass the tool through the loop of the tip of your soldering gun.

Magnets are not nasty unless you sneeze and get snot on it.

I have been collecting magnets for 40 years. I have magnets from old speakers, magnets salvaged from old equipment, large and small magnets all sizes and shapes. They are handy for a lot of thing. I have a 5" magnet stuck on the side of my surface grinder it is so powerful I can not get it off without the help of a pry bar.

Magnets have a HALF LIFE of about 2 seconds just like Uranium has a half life of several 100 years. I can re-magnetize a tiny .625" diameter x .500" long magnet and it will lift 300 lbs for about 2 seconds. Then the magnetism drops to 150 lbs for 2 seconds, then it drops to 75 lbs, then 37 lbs, then 18, then 9, then 4.5, then 2 then 1, then 1/2 lbs and it has returned to its normal power rating. It continues to loose power very slow for ever.

I have a magnitizer that I built. I can re-magnetize old magnets and bring them back to full power. The myth if you drop a magnet or hit a magnet with a hammer it will knock the magnetisum out of it is NOT true.

I also have a de-magnetizer that I built.

I also have an EMP generator that I built. It has a range of about 3 ft and it will totally distroy any semi conductor device in .001 of a second, computer, cell phone, radio, TV, etc.

You can wipe chips off of a magnet with a rag.

If you heat a piece of steel to 1100 degrees F a magnet will not pick it up. Go to your shop and try this. Heat a hex nut or bolt red hot then try to pick it up with a magnet. Keep trying as it cools when the temperature drops below 1100 deg F all of a sudden like magic you can now pick it up.

for the most part im aware of where my magnets are - ever since (back in the day) i was installing a stereo system in my car and placed one of the speakers on my cassette holder bag - thought I had bought a bad stereo when I went to play the music and half of the tapes sounded like someone was turning the volume up and down the entire songs:o

of course that's not a worry anymore - but I still don't want to get one close to my wallet or things you don't really think about much.

I have a nice set of allen wrenches with big handles, which are very convenient, but have always hidden away in a drawer, and all clung together like plastic monkeys whenever I wanted to get one out. Last week I installed a new cabinet in my little shop, and thought "What a perfect spot to hang the Allen wrenches!" The screws supporting them have large enough heads to keep them from falling off the doors, but when the doors are swung open they all rattle and crash as they swing in and out. Yesterday I was into Princess Auto, and picked up a pack of 8 small magnets for less than $3.00 for the lot. I put a dab of glue on the back of each one, slid it in place under an allen wrench with the glued side against the cupboard door. The magnet held itself in place untill the glue dried, and now I have great storage, right up front where I want it, and they don't rattle and crash about when the doors are opened and closed.

Steel magnets, that is. The good news is that neodymium magnets have a half life much longer than our full life - on the order of a thousand years or so.

And they are strong!

The myth if you drop a magnet or hit a magnet with a hammer it will knock the magnetisum out of it is NOT true.
It is true. When I've got a magnetised drill bit and can't be bothered to get out the de-gausser, I drop it onto a concrete floor a few times and the magnetism is gone. The type of magnet that needs a keeper to retain its strength can be badly weakened by a blow. Old magnetos and bicycle dynamos often had a warning not to remove the armature without using a keeper. More modern magnetic materials will not be weakened.

An old tech way of making a magnet was to align a strip of suitable steel with the Earth's poles and strike it repeatedly with a hammer. It will become weakly magnetised. Lay another strip along side and strike it too. It will become more strongly magnetised becuase it's in the field from the first strip. The process can be continued and quite strong magnets built up.


If you heat a piece of steel to 1100 degrees F a magnet will not pick it up. Go to your shop and try this. Heat a hex nut or bolt red hot then try to pick it up with a magnet. Keep trying as it cools when the temperature drops below 1100 deg F all of a sudden like magic you can now pick it up.
It's called the Curie point. Weller magnestat soldering Irons use the effect to control the tip temperature.

Increase the effective range to 100 ft and you could sell millions of them to destroy Rap Crap boomers. :D

I put several neodymium in a 1" diameter dense plastic bottle and pick up metallic chips with it. I slap it on the side of the trash can and the chips all fall off when the magnet moves.

Magnets are real handy in all sorts of ways. In particular they are good for catching grinding swarf.

You know Yod,,, what if - what if you make a roller out of pvc - like a paint roller with a good bearing on one end -- then on the other end is a spring loaded plunger with the next smaller pvc pipe that fits into the larger one - ceptin the smaller one has holes in it and its filled with said magnets -- then you roll the chips up and just pull the plunger (with stop) above the trash can.

YES...The whole movie theater CHEERED so loud and long the manager came to see what was going on. The cell phone woman was in a screening rage and security had to escort her from the theater.
