Key item features

This block magnet measures 3"x1/2"x1/8" and is made of neodymium, the most powerful type of magnet available. It is triple coated in nickel-copper-nickel which gives it excellent corrosion resistance.

Please note that all neodymium rare earth magnets are fragile and require extreme caution when handling due to their brittle nature and to avoid injury due to pinching.
  • Material: Sintered NdFeb. Grade N45
  • Gauss Rating: 13,500 Gauss
  • Pulling Force: 16 lbs
  • Pole Orientation: Magnetized through the thickness, the poles are on the 3" x 1/2" surfaces.
  • Coating: Ni+Cu+Ni 3 layer coating, the best available.
  • Tolerance: The tolerances of all the dimensions are +/-0.002in with coating.

PLEASE NOTE:
  • All magnets may chip and shatter, but if used correctly can last a lifetime.
  • Keep away from pacemakers.
  • Adult supervision advised
  • If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage if magnets join inside the digestive tract.

Fantastic Magnets!

Great! Second time purchasing magnets from this store. High quality. Great instructions for how to use properly. They work SUPER well. I have never had magnets amazing like the ones I've gotten from this company. The strength is phenomenal. You will not be disappointed in how well these magnets are attracted to each other! Perfect for hanging things (instructions on how). The weigh limits of each magnet make it really clear how much each magnet set will hold, so you can buy the right type %26 strength of magnet for your job! I have no complaints. Excellent experiences! Our use of the magnets is going to be different than almost anybody else's, but we have a dog who wears cloth diapers. We have tried for...7 years or so?...to find a way to keep them up. We had a special type of harness-suspender that worked great, but the company is now defunct. We are super careful in how we use them, but she loves them because her diaper-skirt is not falling down and causing her to trip. They don't bother her at all. (She has no metal in her body, of course, or we would not use them.)

Works great

For the crafters out there that are looking to replace your old, small magnets with this one that Jennifer McGuire recommended - go for it. Work great, you will love it.

Very Strong Bar Magnet

I purchased this bar magnet to use with my Misti Stamping Tool. It is a very strong magnet, works exactly as I need it to, and I would recommend it.
