Premium Neodymium Disc Magnets 1.26" x 1/8" (20 Pack) – Rare Earth NdFeB Magnets with Red North Mark for Industrial, Craft, and DIY Use

Earlier this year, I was cosplaying a character with horns that come out of the sides of her head (Albedo, from Overlord), right above the ear, rather than sit on top of the head like most horns do, and come around to rest in front of the forehead. Since they're somewhat odd horns, I found myself in a bit of a predicament in regards to mounting them on my head, not only due to their location, but because of the weight my horns ended up being (after several incarnations, the lowest I got was about 3.5 ounces each; if you can manage really light foam horns, it's a lot easier!).After some researching and trial-and-error, I ended up realizing I needed really, REALLY strong magnets to make this work.Neodymium magnets really are something! Using all 10, the power of these babies can work even through my hand (so if I put one in my palm and let the other 9 attract to it through the back of my hand, the pull is strong enough to hold), so they're pretty powerful. Now, I will say that they're most powerful in groups, so the more weight you want these to hold up, the more magnets need to be stacked together.For my horns, I ended up putting 1 magnet in the base of each horn and then putting a matching magnet inside some thermoplastic attached to a headband that I wore underneath my wig. With four total magnets, my horns were really secure! I could move my head around freely without fear of the horns flying off, and because they're magnets, taking the horns back off at the end of each day was really easy.One trouble I had in regards to using these to mount was that due to my horns having so much in the front, the magnets weren't strong enough to fight against gravity and keep the points of the horns sitting where they needed to. The magnets held them up, of course, but because they're smooth, the pull of gravity was able to shift the horns around so the points kept sinking downward. To counteract this, I added in a thin metal headband wrapped in black thread (to blend in with my wig) that offered enough resistance to the pull of gravity to keep the horns where I put them when the magnets attracted. I think if you could somehow make it so there's enough resistance so two magnets can't turn around on one another you can get around this issue in the event whatever you're mounting has to fight against the pull of gravity.The only other issue was that I had to resort to using a rubberized glue substance called flex-seal to actually adhere the magnets into my horns. Most other glues didn't get enough of a grip and the magnets ripped themselves free of my horns when I went to remove them from the magnets in the headband. The flex-seal was definitely able to grip the most effectively of everything I tried. The alternative would be to actually encase them in something, like I did with the thermoplastic. I didn't encase the magnets in the stuff I made my horns out of (papermache and drywall joint compound) because on top of this stuff being pretty fragile, I also didn't want to lose any of the magnet's power, since it already had to attract to its base through a wig and the more stuff a magnet has to work through to, the less powerful the connection is.Personally, I didn't experience any breakage of the magnets themselves, but they are thin enough that I can see them being fragile if you're reckless and let them attract something aggressively from a distance or drop them on the ground.As for the issue of two magnets getting stuck together without a barrier, there is hope! I found that taking stuck magnets in my palm and sliding them apart was FAR more effective than trying to pry one up and off. You just gotta go slow and stay constant to break the connection and then not let them attract back together. I've had magnets accidentally come together several times while working on my horns and I was able to pry them free each time. Trying to pry them free like you're opening a book will probably result in you ripping off a fingernail or breaking the magnets, if you decide to shove something metal in between them to use like a lever.When trying to figure out the poles, I kept one inside my fist to protect it from snapping up a magnet. They're strong enough that you can feel the pull even through your hand.For the price, I think you get a lot of magnets and that they're pretty great! They're a pretty good size, not too thin or too thick. They worked pretty great for my needs as a cosplayer, so I recommend! Just be sure to test whatever you're doing; wiggle around to see if things succumb to gravity, test how much pull is needed to pry the magnets off things, see if your adhesion method was strong enough to combat the magnets own magnetic pull, etc.

Very Strong N52 magnets, NICELY packaged wrapped in bubble packing in a sturdy box. Could not be happier and just bought more from them. Just bought some of the 1/16" thick as well. I commented on the AD picture about that is was much better to see the product with a picture on a Darker Color than on the usually white background it enhances the contrast to you can see the product better.... Nice presentation.Now that I have had a change to play with these, They are as I had expected "Strong Magnets" Notes to future buyers:* Neodymium magnets N35-N52 in general are brittle.... and because they are very strong magnets will surprise you as to how far away they are attracted to each other. Just the size of these magnets will jump together when the two magnets are 4" apart. They can break if they smack together.* This size is large enough and STRONG enough that once two of these get stuck together, they are extremely hard to get them apart by hand. Hence that is why you see a plastic spacer between the magnets when you get them. If you do not believe what I am saying, go ahead and try it if you think I am bluffing. "Be very careful with small children as this size is of a size for small ones to get pinched fingers and if they break the pieces can be sharp.* Please read everything as to how to put magnets together and take apart safely and save those plastic spacers so you can put them between the magnets when you are done playing with them. I would personally not go any larger size of magnet for children less than 12 years old. And adults you need to be very careful with magnets at 1" cubic inch or larger. These are extremely strong magnets with greater than 90 lbs of pulling force. If you get two of those stuck together you will not pull them apart by hand and will need to make a tool online to separate them. And although they are very thick they can still break or chip off a corner or edge of the magnet.If you write up a REVIEW that the magnets are too fragile you need to look in a mirror to find the true answer as to why it broke. So if you write up a review please look at the person in the mirror before you write up a bad review to say they break too easy.Magnets are very fun for Adults and kids alike but they can be very strong and small and could be swallowed by small children. One magnet not be a problem but if they were to swallow two or more they can cause MAJOR problems so children under 12 is strong encouraged to be supervised by a parent and know how many magnets you started with.With all that said I can say these are great magnets to the point I am going to purchase 20 more magnets. It may also be cheaper if you find one magnet is not strong enough to take two smaller magnets and stick them together to make one magnet twice as thick than trying t purchase one twice as thick to start with. Checking that out could save you some money as well.UPDATED: I have falling in love with these magnets as one of the best to play with. You can make much stronger magnets by just stacking these magnets together. If you use one package of 8 magnets and stack 4 magnets for each larger stronger magnet you can make up two of these magnets for cheap and each magnet will very strong at @75 lbs force each. Save the plastic separators and super glue four of these to make one thick separator between these two magnets. so for about $9 you have two super strong magnets to play with. This is what I would advice before you ever purchase anything stronger, so until you get very good at handling anything stronger is a cheap way to create a very strong magnet. Have Save Fun for Hours.
