Buyer's Guide: Your first neodymium magnet
HTML-код
- Опубликовано: 18 апр 2015
- Neodymium magnets are so powerful that you should watch this before buying one. I give guidelines for size, shape, grade and coating. In this way you hopefully will have a good start with a nice beginner magnet.

I have no personal experiences with magnet webshops outside Europe. For US/Canada it seems that www.magnet4less.com has the best selection at very fair prices. I haven't found any sample sets in their webshop though.
Another cheap source for neo magnets are scrapped hard disk drives. It can be tricky to open the drives though and the magnets are specialized. Here's my video about them: • Magnet in HDD | Taming...

I love this guy's voice! Most people are extremely boring to listen to when given scientific subjects, but this guy has the sort of voice that one can listen to hours for. Great video Brian!
MrNoodless Thanks! I believe I'm getting better at the voiceovers...
***** Yes :)
Say that again. Very good voice and intonation indeed. I also follow an Australia based guy who has tons to tell about electronics. Very very interesting but after half an hour you end up all wind up.
+Kurt Schatteman I think I know the Aussie you're talking about but I forgot his name. All I can remember is he dissembles things like meters and did a tour of a TV transmitter. If that's the same person could you please let me know his channel name. Thank you.
+RMoribayashi it's Dave from EEVblog - just google him...
Whilst the channel is small, the content is huge! I love your videos, they're incredibly informative and terribly interesting! Thanks for taking the time to make these! I really appreciate it!
Luke Paul Thank you very much! Always nice to hear that I am not just wasting my time making these videos :)
Brainiac75 pleas help i am buying 10 pieces of neodymium magnets and and i am being asked about the dimensions so what is the best i am a 1st time user?
+ Omar Taman Hi, you're asking for something I give you guidelines for in this video you have commented on? To sum it up: go for a cylinder magnet that isn't very thin and don't go over 20 mm in diameter for your first magnet.
Brainiac75 12mm diameter and 3mm thickness nickel coating is good because i trying to get 10 pieces and the asked me about its dimensions so?
+Omar Taman 3 mm is thin for a 12 mm diameter magnet. Expect to break a lot of them if you aren't used to handle neodymium magnets :)
I vote for the vid of the macho thing :D
Stefano
Me too!
Stefano i vote for it too!

Challenge - find me the right magnets from here: goo.gl/RUHVQf to enable me to do this: goo.gl/uTHN9Z
+Declan McGuinness
Hi. In the video description for the linked video 3/8 x 3/8" is stated. That is roughly similar to a 10 x 10 mm cylinder magnet which you should be able to find on eBay.
+brainiac75 Thanks very much.
I love the way you warn people. The Ferrari for a first driving test was hilarious.
+Ÿ ^_^ łô
Thank you for watching :)
+Brainiac75 are you German?
BlackSheepTV Nope, I'm Danish.
horrible analogy
@Marvin Connor bot
I came here after immediately pinching my fingers between two small disk magnets that I just purchased. I should have known better, having been already been a subscriber to this channel for a while
Very wise advice even after all these years I still get bit from time to time. Many blood blisters in my past.
So when a friend casually passed a disc magnet the size of my palm and 2 inches thick to me he was amused by the seriousness and respect with which I handled it.
OMG! That is big
Hi Brian, we truly love your videos! They are informative and very entertaining.
supermagnete Thanks for watching and commenting :)
As a diesel mechanic who has worked on gigantic generators that started my career selling and installing upgrades for cars and trucks I can really appreciate the magnet/Ferrari analogy. I was watching this video with my 7 year old who wants to get some magnets because of this channel and you immediately won me over lol.
Where's the best place to get a big square one?
Hey thank you very much, Brian!!! :D I was able to finally buy my first Neodymium Magnet! Im just a beginner, and thats why im very thankful that youve made this video! By the way i was youre 300,000th subscriber! :)
I bought some neodymium magnets that are about 1cm wide and .5cm thick and even when these come together it's hard enough to hurt quite a bit when it pinches my skin. It's also nearly impossible to separate them by brute force, without sliding them past one another. Not to mention how many uncoated magnets I've shattered into dozens of tiny, razor sharp pieces by accidentally letting them snap together. It takes a LOT of vigilance to handle even small magnets like that properly. I couldn't imagine a "monster" magnet.
That was a very well made video. You taught me a lot. Thanks for making it.
My first try is a 1cm disc I bought from a hardware store and I love it.
It's so versatile because of the small size, I can use on everything and carrying it to everywhere easily.
I started off with a 1" cube N52 neodymium magnet. Max 140lbs of force. Seriously a dangerous toy.
i started off with baby 10*6 mm
and now i have 50*50*25mm
(death magnet by its nickname)
tho i bought the N35 version not N40 so it only 50kg not 100
I started with a 30x5mm N45 neodymium magnet that has 23kg pull force.
Well I saw a neodymium magnet with 116kg pull force certainly the most dangerous one
My magnet was the largest disc magnet the website that I used had. (I didn’t use supermagnete)
Do the macho set. I would like that :D
Loved this. Hilarious and practical advice. The Ferrari analogy was pure gold. Keep it up!
I bought a variety of neodymium magnets, the largest having a 405 pull. Following your advice, I began experimenting with the very smallest, a 39 pound pull, 1 inch cup magnet. I have experience with very large ceramic magnets, so I had great confidence.
I now have a small blood blister on one finger, and a greater respect for magnets. Had I ignored your good advice, I could well have had a crushed finger with the largest magnet. Thanks for your fine advice.
Thanks for sharing. Neodymium magnets can be fun, but when measured in whole inches they are not toys :)
OMG! 405 pound pull
Awesome list, Awesome recommendations, Awesome warnings. Nice job and well done!
Excellent guide.
yeah true
Excellent guide to these new type of magnets
Once again a really nice video.
Allthough I' ve got over 2000 neodymium magnets in different shapes and sizes( mostly 5mm balls), it's also a guide for me.
Sorry for my bad English and spelling mistakes, I am German.
Magik Max Thank you! The 5 mm spheres are very popular and with thousands of them you can make nice shapes and sculptures :) And your English is good - no problem.
Thank you for making this safety and information video.
Great videos. Really well done on all I have watched so far.
I've only just come across your videos and of course was immediately off to buy the largest Neodymium magnet I could find.... Then I saw this video.. .Perfect! I then realised I would be making a mistake and set my sights on the Z-13 set as you've shown here. Alas, the 2 companies I've seen you show in your videos deliver outside europe so I'm now off to see if anyone local (Australia) has them. They probably will, at double to triple the price alas. Great videos, informative and interesting, keep em up.
+Terry Wood
Thanks! And yes, shipping neodymium magnets intercontinentally is not easy/cheap. They are only allowed on airplanes in well-shielded boxes. I know nothing about the Australian market - good luck with it :)
Awesome! Relevant today as it was when published six years back.
your videos are always so informative. Thanks for sharing.
Excellent video... And I'm NOT a beginner! Just a great, well presented introduction. Kudos!
+JohnnyJim J
Thank you very much! Experts are also welcome :)
Please do a video on the macho set pleeeeease
Arvid qqu
Need... macho... set... video! :D
Thank you! :) your videos are super informative and helpful.
Absolutely beautiful, Love your videos.
I've bought a set of 50 N52 disk magnets in the size of 10x3mm, and even they impress me very much!
+Seegal Galguntijak
Yes, N52's are impressive no matter the size.
I use Neodymium magnets in my hover board.
Hey, really really really useful video for mortals like me!!! Thanks a lot for the info!!!! You rock!!!
I took my driving test in a Cadillac. You might not think of those as being tough for beginners to drive, but they are. Not because they're fast or squirrely, but because they're HUGE. They're expensive too, especially the older ones.
Thank you for taking the time to make this educational video, especially the warnings. I myself really learned a lot by watching, i never really thought about how dangerous magnet's can be until i watched this video.
Please be responsible everyone, and keep powerful magnet's out of reach of your children, if you have magnets that are strong enough to crush a grown mans hand, little fingers and toes don't stand a snow ball's chance in h3ll.
My pleasure. Small kids and large neodymium magnets is definitely a bad match. I also hope that people are responsible, so everyone is safe and large neodymium magnets are'nt banned.
The way of expressing and your language is understandable thank you for your service to people's
Brilliant video. I am enlightened.! Thank you
You really need to make a video about the Macho set. Very interesting.
nice video and info bro keep it up
Most helpful - thank you!
i bought my first neodynium yesterday and it's a 6 inch magnet, very very expensive but so powerful. I use him to tidy my room's metal items
How expensive
Nuts .
Thanks man good stuff.
Thank you for the video 🙌🏼💯
I'm allergic to nickel. So I'm glad you went into the detail of what they are coated with, thank you.
Gristle Von Raben You can also find some that are zinc-plated. They're very resistant to corrosion too, without being as expensive as gold-plated ones.
Gristle Von Raben You're welcome :)FlipUltraHD's advice about the zinc-plated magnets is a good advice. The 4-layer coatings like Ni-Cu-Ni-Epoxy or Ni-Cu-Ni-Au have so thin layers that even tiny scratches will expose the nickel underneath.
You probably saved my fingers. Thank you for your video.
Very informative video. Thanks.
This is a very helpful video I appreciate it!! Very in detail!
Awesome channel!
+James Cooney
Thanks!
Check out my videos about 5mm small sphere magnets, they're not made for lifting weights of course, but you can do lots of creative stuff with them! ruclips.net/p/PLUlWVEwUd0nD23hIdp0KRDj-j3D6HEIaV
Thanks so much for your reply. I envision the storage of magnets, much like the storage of isotopes, where they store them in "bird cages" (If you Google, you will see what I mean) where the magnets are stored in a binary fashion, but not in close proximity. Perhaps there is more structural safety in such a binary approach? I wonder at what point do the materials break, and what if we just had just essentially a powder instead? Certainly, a mechanical system could be devised to variably bring many individual magnets closer together, and then seperate them. A simple PVC frame could be used to do that, provided that only smaller magnets were used.
How far can you cause deflection of a compass with your large is something I wonder?
This video is very useful
great video i found it very helpful
Because of you im gonna buy a quality magnet. ty very much.
Great glad I watched this first thanks!
your soothing voice is helping my crippling depression during the pandmic. thank you!!!
Macho set! Do a Macho set video! MAKE MORE VIDEOS I LOVE YOUR VOICEOVERS AND SCIENTIFIC INPUT!
We need the macho set video! Now! I can't stand the cliffhanger D:
No ceramic plates were actually harmed in the filing of this video. 😂
I for some reason havnt used tools to separate 25*25 mm disc magnets but i have been fine with them i can easily seperat a 25*25 and 50*10 mm magnet by hand
Am i super strong?
thanks. i have been buying too thin and straight lined. All end up shattering. plus i need to mark the poles. Small thick disc for my next purchase. Tyvm
How would you then classify the magnets used for recovering items dropped in lakes, rivers and streams, commonly called fishing magnets?
I have a 10x25 mm Disc magnet. I had been working with my agnets over 10 months
OK Sure
*goes and buys an 100 mm N52 Cube and opens next to radiator*
I hot an eyebolt magnet that can lift around 120kg
my first neo magnet was 10*6mm rod shape
Since ca. a half a year I have a magnet in my finger.
It's not very useful except for picking or holding up small screws.
However you can feel electro magnetic fields with it which I find really interesting because sometimes you feel it in places you don't expect and in addition it's something a normal human doesn't feel.
thanks for your information
Question: How strong pull in lbs would I need to buy to hold a moving quilt(3/8 inch thick) to my truck(without damaging truck metal)? Making a hail quilt. I have used small neo's on my oil filters for yrs. Thanks
Wow, Amazing video, I have a new found respect for magnets as I tinkered with a few smaller one's and still got BIT, I now know to be far more careful. I pulled apart several hard drives for their magnets and I am amazed as to how powerful they are I can not imagine the really large ones. But I digress...
Great video, yes please do a video on the Super Magnets, as I know in my heart of hearts I fear them now and if you don't do such a video I will never know...
I bought a water cooling kit, used, and it had these very thin, like almost paper thin, 1/16th of an inch or thinner then a typical coin, but they are very powerful as I use them to hold various tools like snipes and pliers. They must me Neo's because they are very strong, I might venture to say probably 48's, if they are 52's I am very impressed. Either way they are round and BIT.
The Magnets pulled from hard drives are very powerful, surprisingly powerful to say the least and I left the metal attached to them as it seems to control their power a lot and makes them far easier to handle. Even with the attached metal shield they are still fun to play with, at least I know I will not crush my fingers with them where as if they are removed from their shields they will be very dangerous to handle.
Thank for sharing this awesome video....
Paul Bialozor Hehe, yes they are surprisingly powerful. They seem so innocent until a large piece of metal comes close to them...Neo magnets from scrapped hard disk drives are a cheap solution. But opening the hard drives and removing the magnets from their brackets is not always easy. And the magnets are quite specialized (my video about them: ruclips.net/video/ep_VCotA1ZY/видео.html). But especially the really old hard drives can have some large impressive magnets.
Thanks for watching and commenting!
brainiac75 Great to know, I have some very old Hard Drives, like 200 MEGs not GIGS, Megabytes... I look forward to dismantling them...
those magnets are no joke, they are so powerful I still have the 12 inch magnets are still stuck together, and I can't get them apart
If you don't mind a 3 or 4 week shipping time then EBay has a boatload of sellers with excellent prices. Most of them are from China and the finish of the magnets are usually not superb but you can get an N52 40x40x20mm square type or a 40x20mm round type for about $15 and shipping is free. The photos are not faked so at least you can see the finish quality and decide for yourself. I've purchased them from Chinese sellers on EBay and am quite satisfied!
Sometimes the dimensions are a bit off. Like maybe you will order a 40x40x20mm magnet and when you get it it's actually 41x37x19 - but hey, that pretty close. And also so far my gauss meter says they are within one rating of what was specified. So if it says N50 on the seller's description then it could be N48 or it could be N52. But in all honesty there is almost no difference between N44 and N52 for example. You can't tell and even the gauss meter has trouble, lifting power is the difference between something like 190kg and 200kg.

Thank you!!!, I am looking at using this (disc type 15mmx3mm) to hold up 2 acrylic sheets frames for posters against the wall, hope it would hold its weight.
You're welcome. Magnets generally don't like shear forces. More info: www.kjmagnetics.com/blog.asp?p=how-much-will-a-magnet-hold
Thanks for the advice! I have a rather specific question about magnets:
I'm building some furniture and I want to encase magnets in the wood to ensure certain parts stay closed or don't move unless a person wants to move them. Any ideas on what kind of sizes would be appropriate?
That depends a lot on the design, weight of the objects etc. Magnets are easy to shear apart, but hard to pull directly apart. You need to experiment with it.
Very very good. Cant give you enough thumbs for this one. Good advice, not lame choices.
gamingSlasher Thank you very much. Glad that you think I made a fair compromise between safety and power :)
how much do you think a N35
50mm×10mm disc magnet will lift??
17kilos on rated box but maybe wrong
I like these magnets I want to get some more I have small ones. They can be really useful!
In my opinion, a long cylinder would be best for a beginner. They are easy to handle because they have a lot of room to hold on to, and can be most easily controlled when letting it contact another magnet or metal surface. I like cubes and blocks for how they look but a long cylinder is most easy to casually play with. I carry a .5x2 inch cylinder magnet with me and it handles pretty nicely. Though do be careful what you set on your lap when carrying a magnet around, I almost ruined my laptop fan once.
+KingofHearts67
Cylinder magnets are the easiest to handle, no doubt about it. I just have trouble with recommending them since you pay for a lot of length of magnet that is not really adding much power. A 10x40 mm cylinder magnet is 4 times more expensive than a 10x10 mm disc magnet. But it is far from 4 times as powerful, only around 20% more pull force... So measured in power a cylinder magnet is not good value for money. It's still a nice magnet though :)
Just bought a 4" OD x 2" ID x 1/2" thick Round Magnet to strap on my back to hold random work tools. Have I made a mistake?
What do you mean by a "thick Round Magnet". *Laughter*.
He was so true. I bought two 20x20x10 square neodymium magnet. and I tried to seperate. Neodymium magnet was so strong. neodymium magnets pinched my skins with sharp corners. that was so hurt :(
So buy MUCH SMALLER than YOU THINK.
and I need to learn grammar
Where is the best place to buy them? I need some for generator experiments 1 to 2 inch x 1/2 to 3/4 inch.
I bought a few "small" ones a while back. And they were surprisingly powerful....and painful!
Hello
I am so used to getting pinched by big ones that i kinda feel nice
@@TheRadioactiveBanana32 even Alnico is giving me pinch i bought disc magnets of 90 mm * 36 mm * 15 mm disc Alnico magnets and it's giving me pinch whenever i try to stick them together.😭
1. Do you know where the magnets in the kits you show are manufactured?
2. Are magnets typically marked with the North and South poles on them? If no, why not?
Thanks!
Hi Brian, thanks for this informative piece, I have now got lost in Wikipedia entries on Neodymium and REE !!
I was really looking for a way to remagnetise my aquarium cleaner magnets. I do have some old hard drives that I need to put beyond use. Would the magnet from a hard drive be strong enough to re-magnetise the aquarium magnets? They are a pair of 5 x 3 cm rectangles probably 3mm thick and bonded to plastic holders
How about a n35 disk magnet with dimension of 1cm x 0.3cm?
Can it have high attractive force(8kg> between two of them?
I need a magnet that can fit under my pant leg unnoticeably and strong enough to move a fork from the underside of a table what should I get
i bought some 20×15 cylinder magnet. i really underestimate their power until one if em start flying so fast and broke it.
They are really strong people.
like *really* strong
I have a small amount of experience with neodymium magnets (the ones from i believe a printer) and I am wanting to get one for fun thanks.
It just so happens that there are a few warehouses of neodymium magnet stores here in Texas where I am, in fact in the same town that I am in. I can literally go over to the place and buy magnets straight from the store. It is the Applied Magnets store. You may have heard of it. There is another one that I do not immediately remember. Applied magnets at one point sold 1/2 inch grade N54 magnets.
+QuestionXV Lucky you :) And yes, I did see the N54 magnets they advertised with. But they quickly stopped selling them - were they underspec or just a one-time offer? I don't know.
Here I am over a year later, I'm still amazed that I have one of the biggest neodymium warehouses in the world less than 15 miles from my house, I live in Plano and the warehouse is at 1111 Summit Ave #11, Plano, TX 75074, and there is another warehouse, the one for CMS Magnetics, 1839 Wall St, Garland, TX 75041. That should give some people here excuse to move to Texas, by the way, congratulations on almost 200,000 subscribers.
Thank you :) Yes, and I still have to import the magnets from another country if I want a decent size...
Is it a good idea to wear rubber while using magnets or should I stick to the leather harness?.
Gotten my set coming in the mail, followed majority of the guidelines you stated, probably somewhat of a slightly larger magnet (.56 in^3) but pretty close.
As long as you're prepared and don't start with slamming the magnets on a large piece of iron with your fingers between, you'll be fine :) Thanks for watching and good luck with the magnet.
Brainiac75 Well they arrived today, probably my happiness took away part of my preparation as putting them on a table and the magnets swiping around the area ends up two chips from two of them coming off. I decided to put the two that shattered away to keep them away from moisture so they don't corrode as quickly. Well thanks for the good luck, although maybe a shatter there's always plenty of time to get better handling the magnets. :)
Can someone recommend a magnet intensity for me to use for a project? I’m creating a large staff weapon, but I want it to be collapsible into two pieces for transportation. I want to put magnets in the two halves of the staff, that will hold together while walking around with it, but I can separate when I need to. Is 52 too strong? The staff is very long, 7ft+, but thin in structure like a pole and made of acrylic
Actually there's is a cool magnet shop in my country, I usually buy little magnets from them. I just walk in, say what I want the magnet for and they can show me how they look, I can change my mind and pay. I don't buy much magnets but when I need some I know where to look :)
Nice, we don't have such a store in Denmark. For me it would be funny to visit one :D
What’s the relationship between “lifting” strength and “repelling” strength ? If you can lift 20kgs, then in repulsion of 2 could they levitate 20kgs?
I bought an 30 x 10 disc magnet and 10x10x10 square magnet as my first neodymium magnets
Lol det var først 2-3 dage efter jeg subscribede til dig at jeg opdaget at du var fra Danmark...
i was sorta of beginner but i still bought 150x50 N45 disc-shaped neodymium magnet... and i can say it was a mistake... despite i clearly understood it's power i cant really handle it at home cause it attracts metal objects in 1 meter radius... however its fun cuz that thing can lift up to 100kg while being separated by 20 mm wooden table. Also throwing a metal grid on this beast with a apple on it slices it in little cubes in no time :)
U dumbass
There are some weird shape very strong magnets in a hard drive, if you open the case. They are much stronger than fridge magnets, but I doubt they are close to Neodymium or other rare earth metals, but I don't know what are they made of.
thank you very well made video
