The Correct Way to Separate Your Applied Magnets Products !!

CORRECT 1. Slide one magnet off the top of the stack. 2. Once off thestack,carefully start lifting the magnet. 3. Lift the magnet to free it from the stack.

INCORRECT 1. DO NOT attempt to pull, lift, or pry amagnet from the stack before sliding it to the side. 2. DO NOT throw away the white storage spacers. 3. DO NOT allow the magnets to snap to each other or any magnetic surface. doing so may cause magnets to break!

BE CAREFUL !!!

1. Keep away from pacemakers. 2. Powerful magnets can hurt your fingers. 3. Not for children, parental supervision required. 4. All magnets may chip and shatter, but if used correctly can last a lifetime. 5. If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage.

User questions & answers

Question:	Is there a women's version
Answer:	It is nickel plated and I am sure it can be etched. It is plated because the neodymium is reactive and will corrode. Neodymium magnets have poor resistance to corrosion and they can also corrode from the inside-out if proper pre-treatment processes are not followed. Oftentimes, multi-layer Nickel-Copper-Nickel plating is applied to prevent failure from corrosion, but this preventative technique may not be sufficient for all applications. Corrosion Mechanism: Fully dense* Neodymium Iron Boron is made with a powdered metal process. The quality of the powder dramatically impacts the resulting Neo magnet’s magnetic performance as well as environmental tolerance. Appropriately sized, well-formed powder grains which have little un-reacted constituent elements will result in highly performing magnets. Even magnets made with ideal powder will still have some un-reacted components which will oxidize or rust. (Poorly made magnets may oxidize from the inside out.)

Question:	Can this get wet? i.e go into the pool/ocean or take a shower with
Answer:	Considering hundreds of double blind tests and most scientific information available, no, these can't be used for magnet therapy because magnet therapy was made up so someone could get rich by selling magnets to suckers.
Question:	Does this item have actual carbon fiber? It looks like a sticker
Answer:	Grades of Neodymium N35, N38, N42, N38SH...what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH. You find the temperature rating of each grade on our Specifications of Neodymium Magnets Page.
Question:	Is there a way to auto include more links with the bracelet for those of us with larger wrists? Mine is about 10 inches (25.4 cm) in diameter
Answer:	Short dress but lovely

User questions & answers

Question:	Manufacturers shipping to the UK
Answer:	Answer) Hi there and thanks for your question! There shouldn't be any issue with water at all. If showering or swimming, just be sure to rinse the bracelet off afterwards to remove any soap/chlorine, etc. It’s also helpful to dry it afterwards as well. Many of our customers wear the bracelet 24 hours a day and never take it off. You shouldn’t have anything to worry about rust. Long term though, it may be best if taken off before swimming or showers, if it’s not an issue for you. Rest assured if there are any problems because of this, reach out to us and we'll make it right. I hope this helps! I represent the Smarter LifeStyle brand.
Question:	At what distance does this magnet start grabbing say .5" neodymium magnet? Im trying to fish a wire behind exterior wall of a house
Answer:	The carbon fiber is inlaid into the bracelet and seems to have a glass covering over the inlay which gives it that look. Completely different in person than pic. Bracelet does not have a satin or flat look. It is glossy, nothing like the pic above
Question:	Using K&J's calculator, a magnet of this rating and size should only produce a peak of 320 pounds of pull force. Why is this magnet twice as strong
Answer:	Hi and thanks for your question! We can definitely provide extra links! Just send a message through your Amazon order, requesting the links, and providing your mailing address. We’ll be able to send them out free of charge. Each link adds about 0.4 inches to the bracelet. Please note that we send the extra links separately from the Amazon shipment, as they are sent from a different warehouse. I hope this helps! I represent Smarter Lifestyle brand.
Question:	Will this magnet hold in place a Bird House with 3/8 inch thick wood sides that weighs 3 pounds, to a flat steel plate 1/8" thick
Answer:	the repel force roughly equals 1/3 of the pull force. so no it would not be 1200 Lbs

• 1" ROUND MAGNETS ARE IDEALLY SIZED FOR MANY PROJECTS. They are the best size for bottle cap craft - no glueing necessary as they fit perfectly, and they make super refrigerator magnets as they are smooth and flat. These high strength ferrite magnets are are a little larger than most craft magnets which can be too small and not strong enough. Imagine the possibilities for household, school, office, lab, manufacturing and hobby projects.
• HIGHLY VERSATILE - You can paint, varnish & glue these heavy duty buttons and they will not rust so ideal for outdoors & submersion in water. Heavy enough for using as weights in table cloths and can clamp shower curtains to a metal tub. Also great for organizing and storing tools to keep your work bench clear and they'll even hold on to your nails while you're working!
• YOU WANT RELIABLE & STRONG - They can firmly hold through 12 sheets of A4 (80g) paper on a magnetic whiteboard or in your locker so essential for keeping your notes in order. These are Grade 5 so you know they have enough power to fix that pesky cabinet door that won't stay closed or store your spice bottles under a shelf, and they are cheaper than rare earth neodymium circle magnets so you get a lot of magnets for your money plus you save even more with your bulk set of 100 pieces in a box.
• WE BELIEVE IN QUALITY - Giving our customers the best experience we can and empowering them to success. We use our ferrite / ceramic magnets so we know what works and we listen closely to our customers needs.

User questions & answers

Question:	Has anyone used these for outdoor curtains
Answer:	Hi Ryan.Actually the distance depends on the material of the wall (brick, concrete etc.), the thickness and material of which the wire is made. Normally its about 1-4"
Question:	Country of origin
Answer:	Magneto flunked basic physics. Just because it can pull with 300 pounds on one side and 300 pounds on the other side, it does not add up to 600 pounds. If you place the magnet in line with two heavy ferrous pieces with perfect attachment, you still will only be able to pull with 300 pounds.
Question:	Would this be strong enough if embedded in 1/8" pine, to another magnet in pine, so going through 3 inches of pine? simple children's toy
Answer:	This magnet is too strong for your application. Why would you choose a 600 lbs pull magnet to hold a 3 lbs birdhouse? Get a 20 lbs magnet. The first time you try to mount your birdhouse using this magnet it will pull itself out of your hands and slam into the steel plate so hard that it will likely destroy the birdhouse just from the impact. The birdhouse pieces will then fall to the ground and you will be left with a magnet stuck to your steel plate that you cannot easily remove. Pull it to the edge and try to twist it off. Wear gloves. If you get desperate and don't mind destroying the magnet then you can use a propane torch to heat up the magnet. At some temperature below red hot it will fall off. When it cools it will regain only a small fraction of its original strength. Should you get the birdhouse attached without destroying anything or hurting yourself then the intense magnetic field could possibly play havoc with the navigation sensory system of migratory birds that might nest in your birdhouse for the Summer... I had a magnet that was 1/3rd the size of this magnet and I accidentally let go of it near a steel vise and when the magnet hit it exploded and shattered into a few big chunks and hundreds of little razor sharp shards. These things will break your fingers. They are no joke. Get a smaller magnet -- a much smaller magnet.
Question:	How long do these magnets last? I want to add these to a costume but im afraid they will lose their magnetic properties
Answer:	Hi there and thanks for your question! Unfortunately at this time we don't have any women's specific versions of our carbon fiber bracelets. However, we've had some female customers purchase these bracelets in the past. I hope this helps in your research! I represent the Smarter LifeStyle Brand.
