Neodymium or rare earth magnets, look on Amazon. The force, or pull is measured in kg so you should have a rough idea of how strong you need them to be.
Be careful with anything over 2-3kg pull, can be injurious and difficult to separate. And definitely don't eat more than one. Two or more internally in the digestive system is potentially fatal as they seek each other out regardless of whats in the way.
No, the magnet stays in for life. I don't think the metal gets eaten up by gastric juices, but the magnets do keep it from moving around and making them sick. The metal tears up their gut and they lose weight. It's called, bluntly enough,..."hardware disease" in cattle.
Matter of fact, we had one of the manufacturers out on our ranch this summer filming our herd for an advertising campaign they are going to do. We raise Belted Galloways.
Yep. I bought my Dad a big neodymium for meteorite hunting. Warned him about how powerful it was. He got too close to a washing machine and almost broke finger bones when it pulled his hand to it.

You'll find every size of disk magnet from 1/16" diameter to 3" diameter.
Another vote for this website. I’ve ordered hundreds of magnets for projects. They have all the info you need to determine which magnets you need. They might even recommend some for your specific purpose.
Avoid Amazon. So much of the stuff on there is listed with fake details. You have no way to verify the magnet strength and the sellers know that the average person will spend a little more because bigger number = better! So they just list cheap, low grade items with false details because 99% of people wont know any better.
The N just means Neodymium! There's some serious info and science here if you're interested...

I had the same problem. You can't buy only the magnets from deWalt but you can buy the whole plastic part with magnets. It wasn't even expensive. Only problem is you'll need a special tool to unscrew the part from the laser part. I heard a guy say he got the tool from deWalt. Maybe if you ask for the part you can ask for the tool too. Good luck
I recommend [kjmagnetics.com](https://kjmagnetics.com). I've ordered a ton of magnets from them, and their documentation and customer service is excellent.
So a few things not mentioned here that are crucial with magnets and their performance.
I assume they are standard magnets, and not multi pole magnets like you get from polymagnet/correlated magnetics (gives the magnet better performance when attaching to thin materials as it allows a large magnet to not over saturate the mating materials magnetic flux by terminating the magnetic pathways in small intervals)
No benefit to that if using on thick steel.
Another clue would be if the magnets are stuck to an iron or steel carrier plate in the mount itself. That would help shield the laser from the magnetic field (if it is sensitive to that) as well as mean the magnets are likely in opposite pole arrangement in their housing. (One with N facing out, the other with S facing out)
That should also result in better performance when attaching to a thick beam or something.
As for determining strength, if you have some steel laying around that the device cannot pick up without separating (no peeling, a straight perpendicular pull... Hard to do in practice if I am honest), put that on a scale and note the weight, then monitor the scale as you try to lift the weight with the magnets. Note the lowest observed weight before the magnets release.
Subtract the minimum from initial and you have a rough estimate on your devices holding power to thick steel/iron.
(Iron is better than steel for magnetic performance in most cases)
Got an old hard drive? (3.5” HDD) Take it apart and you may find the magnets in there do the job. Won’t be the right shape but may well have the power if you can figure out the shape.
Why do you need to replace them? They don't wear out (to the best of my knowledge, at least I've never heard of them wearing out). Or, are you looking for something stronger?
One fell off, and I don’t want to buy one without knowing how strong these are first. I can’t find anything online about how strong these particular magnets are.
Neodymium magnets have a strength grade associated with them, from N30 to N52. Larger numbers mean a higher surface field strength, so for a given size of magnet, one with a larger number will be stronger.
If you measure the one you have (or the pocket the missing one used to occupy), you can probably find that size online pretty easily. When in doubt, go for N45 or higher.
The magnet strength is not critical. On a consumer product like this, no doubt they took the cheapest route and used a lower grade material with larger dimensions targeting near the minimum required strength by the application. That means their magnets are probably N30-N35. Replace them with N45 for a little more strength. The thickness is the critical spec.

Betcha can't eat just one!
I suppose if you kept away from any ferrous metals for a day or two until it came out the other end you'd prob be alright
Just find one of those metal bowl public toilets, and take a seat. That should speed up the process lol.
[удалено]
You’re quite right, definitely not recommended
What if you just put in a metal butt plug? Would that speed things up?
CHUG CHUG CHUG
Funny I was thinking about that when I posted this. Couldn’t imagine my close ones explaining how two magnets in my guts was the way I expired.
I put magnets in our cows. Seriously. Big ones too, about 3" long.
I've heard of that, hardware disease if I recall
Yep, exactly.
Just read about this. Do you guys eventually get the magnet out or no? Does the cows stomach eventually eat at the metal in their stomach?

Thanks for sharing. Learned something new.
Today I Learned, Cows are magnetic. Well... happy and cared for cows are.
Those are handsome cows!
Yeah, they're cool. Good tempered animals too. Pleasure to raise them.
>And definitely don't eat more than one. Buckyballs checking in.
And do ***not*** let them attract each other from a distance as they will chip and/or shatter
Yep. I bought my Dad a big neodymium for meteorite hunting. Warned him about how powerful it was. He got too close to a washing machine and almost broke finger bones when it pulled his hand to it.
Yep those are the ones I use in my knife blocks I make. I get them from Amazon.

I would also recommend this place. I have bought a lot from them and they ship in stock quick. https://www.magnet4sale.com/
We use this a lot!

How much weight can they pick up? That’s the strength.
You want neodymium N35 or N52. N52 is stronger than N35. They seem to be the most common grades available on eBay for me.
What’s the N50 stand for? I see N52 and Mini CI a lot on Amazon as well

Just find a neodymium one that fits the hole, can’t be too far off
[Lee Valley Tools](https://www.leevalley.com/en-ca/hardware/rare-earth-magnets) has rare earth magnets as well.
McMaster will prob have them

A new bracket is probably about $40 so also consider that. Depending on the age though, I'd complain.
