Super Strong N52 Neodymium Magnet 3 x 1/2 x 1/4 14 lb bar, The World’s Strongest & Most Powerful Rare Earth Magnets by Applied Magnets

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.

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....

Very Nice. Strong. a very small but, OK. i wish they sell a biger one. :)

The magnet works well, but these were advertised as being a 2 pack in the title when there is only a single magnet in each order. I placed two orders but only received one magnet per order instead of the total of four I was expecting.

Broke about two minutes into having it. Pretty fragile magnet but very very strong.

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.

N52 not. Too thin and weak. Not worth it.

!!! WARNING !!!I bought 2 of these magnets.I opened the packaging, placed 1 magnet on refrigerator, placed our really heavy calendar over magnet, placed 2nd magnet on top of calendar over the pre placed magnet, Holds awesome!!!Here is the warning, I couldn't take calendar off refrigerator. I had to Slide calendar & 2 mags off edge of refrigerator. 2 Mag's are now one. I cant separate them, so, I have 1 magnet now & I'm ok with that. My fault.You have been warned!
