## Description

Product description INCREDIBLE NEODYMIUM STRENGTH Applied Magnets Neodymium rare earth magnets are stronger than the strongest ceramic magnets! With a grade of N42, each magnet packs a huge magnetic energy punch and will last forever under normal use. APPLIED MAGNETS Applied Magnets is able to offer you the high quality Neodymium magnets with consistent performance. This Super Strong Neodymium Cup Magnet is extremely powerful and built to last. It’s designed & manufactured under stringent, top quality standards using the latest technology to ensure you receive the best Neodymium Magnet every time. Pull Force Pull Force is the amount of force required to separate 2 of the same size magnets from each other. Actual pull force of cylinder/disc magnets may vary depending on different applications due to the small contact surface, please test them before usage. Rule of thumb is that the magnet will hold approx. 1/3 the weight of the stated pull force. So...If pull force stated is 90 lbs...the magnet will hold approx. 30 lbs in weight hanging from it. How to SAFELY separate your Applied Bar Magnets ! ! 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.

Review: Strong magnet for dog door - I purchased these magnets for the dog door to increase the strength of the flap adhesion since the cats recently figured out how to use the door as well. First round of cheaper magnets of the same size (different brand) did not work. These magnets have increased the strength enough to thwart the efforts of the cats while still alowing ease of access for the large (70 lbs )dogs. Definitely recommend.
Review: I bought this magnet for a very specific application. ... - I bought this magnet for a very specific application. I am an electrician, and it is quite common for the sheetrockers to cover my electrical boxes. I wanted this magnet to locate my boxes behind their sheetrock. It works fairly well, I just wish it was a bit stronger than it is. Also, maybe I should just use my hammer to find my boxes....

Wrapped really nice. Loved that it was deep in bubble wrap. I used it right away to test silver. Worked perfect. Thank you. Really nice. Wrapped back up in bubble wrap and placed in box for safe keeping until next silver purchase.
