CMS Magnetics 1-Inch Neodymium Cube Magnet | Strong NdFeB Rare Earth Magnet with Triple Ni-Cu-Ni Coating | Durable & Powerful for Industrial, DIY & Educational Use, Safe Keeper Included

be careful

The Neodymium Magnet I purchased is unbelievably strong. It's imperative you heed the warnings that accompany theses magnets. Also called Rare Earth Magnets, they are delicate. Unbelievably strong but can shatter if allowed to snap/crash into each other. I have over a dozen. One cube, the rest - 3-inch bars. They pinch, they hurt when they pinch, they snap together with force, which also hurts, unless you follow the manufacturer's safety instructions. I have shattered three of this type of magnet. They are as dedicated as they are powerful, which probably sounds weird, but buy a couple if you wish to know what I'm talking about.

Arrived timely as always. My order of this magnetic cube did sport a red dot but it will fade quickly so just use your own permanent marker if you like to mark the head pole. Plan on being pleasant satisfied with your purchase. I think this size and force strength is ideal if you are new or unfamiliar with exceptionally strong magnetic fields. Use these with CAUTION! whether tinkering or experimenting because it does pack a bit of a snap when around metal but you will be just fine. Just make sure that YOU are alert when handling these. I plan to graduate up to higher Gauss Strength magnets after becoming more familiar and measuring what can be done compared to what NOT to do with these to avoid issues. UPDATE: Well I did it. Another different new purchase of an even Stronger Disc Magnet instantly detected this CUBE and went straight for it when I got too close. I keep mine on a steel door. The Disc Magnet fractured this CUBE in 2 parts so i'll soon be ordering another one again (Hah Ha). The fractured CUBE is still as POTENT! as if it didn't break! These are superior grade and quality magnets. I won't be repeating that dumb maneuver again or Amazon will really love me with extra replacement orders. Enjoy your purchase. I will be ordering again from this supplier but will also be exercising the greatest of caution every step up from this one because these have what it takes!

Very strong magnet. The red stripe marking North Pole rubs off with use. The only thing preventing a five-star: I would like to know magnetic field strength for a magnet this expensive. To really hit it out of the park, you could list magnetic permeability and saturation for materials properties enthusiasts! I was able with this magnet to saturate the ferrite shield in a Qi charger and trigger the fod error from the far side of the shield.

After having just taken an advanced physics course, I was excited to experiment with magnetism and these seemed like the perfect magnets for what I was wanting to do. These seemed to be such a reasonable price, I figured I'd order two. Because, you know, two is always better than one, and if you're ordering two, I have some very useful advice for you: DO NOT ORDER THEM TOGETHER! Or, if you do order them together, don't be stupid, and use common sense (unlike me) and DO NOT open them at the same time, right next to each other... sigh. I missed all the warning signs that were trying to tell me it was a bad idea. Truly. The first was when I noticed the two containers (very nice containers for how much they cost) were sticking together. No, there wasn't tape or glue keeping them together, it was the magnets. That's how strong they are. That was the first sign warning me not to open them at the same time. The second came after I opened the first one. I pulled out the magnet, which came out unwillingly. He was ever-so attracted to the metallic container from which he arrived inside of. But after a good talking to, he decided to come out. That's when he noticed the second container, and practically (but not literally) jumped out of my hands and onto the other container. I thought to myself "wow, these things are pretty powerful", which is an understatement. I had two warning signs staring me in the eyes telling me "DO NOT OPEN THAT OTHER CONTAINER!", but, like a kid in a candy store, or an adult on Amazon, I had no self-control and was oblivious to these warning signs. I set the first magnet down about 3 feet away from anything that it was attracted to, and was ready to open the second container. I picked it up, opened the top, and began to wrestle with the magnet inside to try and get it out of the container. As I was lifting it out of the container, I thought to myself "I should probably keep these magnets separ-" and before I could finish that thought, a shiny silver object came flying across my face and quite literally knocked the magnet out of my hands and launched it across the room. When the two magnets collided, one of them completely shattered (the material they're made out of is soft/fragile). Even though it had shattered, it was all still being held together by the insane force of magnetism it wielded. Now, I had one solid, in-tact cubic magnet stuck to one not-so-in-tact somewhat cubic magnet. I figured I'd just pull them apart. HA! Nope! Not even close. When they say these things take over 90 pound of force to separate, they aren't kidding. After several YouTube videos and web-surfing for hours, I was almost ready to decide that I was okay having a single rectangular magnet, but I finally figured out how I was going to separate these. Almost everything I read suggested using a table edge to separate them. However, getting them separate (but still connected at the corners) proved to be incredibly dangerous. I could hold them in this position, but the second I tried to move them away from the table to completely separate them they would smash back together, nearly trapping my phalanges forever. So, when I got them in that position, I decided to stick a thick blanket between them and let them clamp down on it so that the blanket would remain between them. It worked, and I was able to slide them toward the center of the blanket (while also ruining the blanket), and wrapped one of the magnets completely with the remainder of the blanket. I then tried the table trick again. I put the exposed magnet on the table, and the (literally) blanketed magnet off the edge. I separated them so they were only connected at the corners, and was ready to give it my all. One hand was holding down the magnet on the table with every ounce of strength I had left in that arm, and the other had a firm grab on the end of the blanket. With all the effort I could muster up, and nearly tearing my pectorals, I forced the two magnets apart successfully! I immediately threw the open magnet away at one of my couches and sprinted into the other room with the blanketed magnet. To this day those magnets have yet to be in the same room at the same time.

I have a 1998 Oldsmobile. All the gauges are analog. The battery died and stayed dead for quite a long time. When I got around to putting in a new battery, I saw that the fuel gauge needle had spun all the way around and was now pointing straight down. When I put fuel in the tank, the needle went up until it hit that pin that sits at the "E". While talking at a mechanic friend, he said that a magnet would fix this. ?!? really? So I grabbed all the magnets I owned and tried it. None were strong enough to move the needle very far. But I did see that they *DID* move the needle. So, I ordered this one. I needed a super strong magnet that I could hold in one hand and this fit the bill perfectly. I love how it comes packaged...suspended in the tin in a foam cage. Necessary because once this thing latches onto metal, it's not easy to get it off of the metal (I lost a super strong magnet because a truck drove too close to my garage one day and the magnet went flying like in cartoons...I had to sign a waiver to purchase that thing....) Anyway. I put this magnet near the needle and it moved quite a bit! I waved the magnet back and forth and was able to get the needle to swing back into position. Yay! Magnetism FTW!

Stunning when you first really start to comprehend the strength. It has a great presentation with quality component parts for the relative affordability of it all. I really enjoyed it. Do not have your phone by it, computer, old tv etc. If you wear nice mechanical watches and even think they have resistant balance springs I wouldn't risk it as these are very magnetic. So if giving as a gift make sure you tell them! They are fun and amusing

Absolutely DO NOT purchase this magnet if you don't have the proper respect for just how powerful these things are. These magnets have monstrous power and the utmost care is to be taken with them, ESPECIALLY if you have two or more, do not even let them get close to each other while they are in their own separate cases. This magnet has a flawless finish, edges have been taken off nicely too. Perfect for picking up tiny objects out of grass or even dirt, or just stick it on the wall and have it hold every screw ever made. Just remember to wrap your magnet before picking up small objects or you will likely never get all the particles off ever again.
