Super strong magnet for the money. Being a back yard mechanic I’ve used it multiple times to find to find bolts and parts I dropped in the grass from my boat and cars. It’s already paid for itself twice in the time and money it’s saved me getting new parts. The kids had it stuck on the fridge and climbed up the side, the only way I got it off was by sliding it to the side. Don’t let your 5 year old play with it!

HIGH QUALITY DESIGN - The neodymium round base magnet is made of a super strong neodymium magnet encased inside a chrome plated steel cup. With the magnet force centralized on the bottom, allowing the other three sides to be sealed, protecting the central magnet from outside damage.Also the eyebolt provides very easy use, but for example you can replace it with your own designs such as a hook for hanging objects inside your home.
This is my first magnet like this and consider me impressed! It is well built and super strong. I thought I would attach it to the frame of my power rack (thick metal) to see just how strong it was. That turned out to be an err in judgement on my part. After considerable force and a few scratches it finally slid off but wow.....it did take a lot effort.
NdFeB Pot Magnets are best for small sized magnetic products with maximum pull strength (ideally when in direct contact with ferromagnetic e.g. mild steel surfaces). The actual pull force achieved is dependent on the surface that is being clamped onto (material type, thickness, flatness, friction levels, etc), its quality (e.g. rust free), its size (thickness plus total surface area), etc. There are many applications for NdFeB Pot Magnets, mainly in applications where a strong clamping force is required. Applications include Point of Sale, windows dressing, door / cupboard and gate clamps, false ceiling clamps, signs and banners, torque limited seals, jigs and fixtures, lighting holders, marketing and exhibition displays, retrieval magnets, industrial fixings, etc.
This magnet is strong! Not sure how much weight it could actually hold, but it takes a good bit of force to get it off of anything it is stuck to. I was actually kind of worried that it would be too strong and I would be able to get what it is holding off, but it's just right. I would highly recommend to anybody looking for a strong durable magnet. DIYMAG has them packaged with a lot of protection and warnings in each box to let you know what can damage the magnet. I have even already recommended this to friends as this is higher quality at a better price then what I could find locally.
This is a very strong magnet! The item was exactly as the seller described. Pull force measurements based upon the testing protocol used by the manufacturer look to be accurate from my uses however I did not replicate the seller's test protocol. The pull force of a magnet is directly tied to the material that is interacting with the magnetic flux lines of the magnet (more generically the magnetic field). Put very simply, the bigger a given type of magnet is, the more area its field can interact with vs another piece of material. If you attach this magnet to normal construction steels with a flat face that is larger than the surface area of the magnet like say an I-Beam or thicker construction steel strips (1/4 inch or above) you'll get quite a workout removing it. If you cover only the center of the magnet with said materials it will take work but much less. Please note most easily accessible stainless steels aren't great for magnetic force tests. Put this next to your average stainless steel bowl or drinking cup and it will barely attract. However if you have high quality stainless steel cookware designed for an induction stove the base will stick to this magnet like glue due to an embedded induction plate, usually of iron. Science does have its uses sometimes :-)
I’m new to magnet fishing. A friend of mine and I go magnet fishing on his boat and he has a set of magnets for me to use. They are round disks about 3 to 3 1/2” in diameter with thick magnets Inside. Three on one side and two on the opposite. Me,being 5 ft 1, 104lb, 41 yr old woman, gets pretty sore after many hours of throwing this set of magnets as far as I can into the middle of the bayou. I decided to buy my own magnets. I had enough extra money for one magnet so I got this one because of the pulling force and figured l could get more later. When it finally arrived, I was so excited and I took it out of the pkg and was like “seriously”? It’s so small, I’m going to get laughed at. I call my friend to let him know my magnet came in and he informed me that his son bought him a new magnet for Christmas. His magnet was more than double the size of mine. I was blushing and told him that size didn’t count and he’d better not laugh at my magnet. Now it’s time to test them out. My magnet is super light and I’m worried about it not sinking with the strong current and undercurrents. Well, in no time at all, I feel it pull to something and stop moving. I start pulling in and whatever I’m pulling on seems really heavy. It was a metal side rail to a bed plus some old cast iron nails attached to it also. I was so excited, I wouldn’t have been able to spell sh*t with three pencils. I ended up pulling more and bigger things than my friends did!!!!

This magnet is super strong, well made and if you get it close to metal you better hang on because it's going. I purchased for the sole purpose of using it to reset my TPMS but the magnet is so powerful I went ahead and was able to use it to pull out a couple of shopping cart dings in my car. I absolutely recommend this magnet, it is sturdy, heavy and will last a lifetime. Be sure not to leave this close to computers, tablets etc... the pull of this will definitely fry some motherboards..... 5 stars
Not satisfied with this, we figured that we should show up at the lake with some bigger, stronger magnets that would be ridiculously strong.  For the monster magnet picker-upper, we bolted three MMS-B-Z0 magnets across a length of aluminum extrusion, and tied that to our rope.  This setup is a lot more powerful, so we did worry about it getting attached to something that would exceed our ability to pull up with a rope.

The best knot to use for magnet fishing is one where it tightens on itself, providing a secure hold on the magnet. Also, the knot needs to be one that is able to bear heavy weight. If you are a fish angler and have a favorite knot, then try using it for your magnet. For first-timers, we recommend the trusty Palomar knot which is very simple to tie and is considered by many to be one of the strongest knots.
