Tube of 20 Neodymium Magnets

Tube of 20 Neodymium Magnets

    Item #020


    Our mighty 4mm cubic rare earth magnets are incredibly useful, mesmerizing to fiddle with, and a steal for only 5 bucks for a tube of 20.

    We had these custom manufactured to the highest magnetization the factory could concentrate into the small space. 

    Made from a neodymium (Nd) alloy, these magnets each have about a 4lb pull (direct metal-to-metal contact). They are nickel coated since the magnetic material is a highly compressed powder. 

    *NOT A TOY. NOT FOR YOUNG CHILDREN. DO NOT SWALLOW*

     

    More info:

    Only a few elements are naturally magnetic at room temperature. Neodymium is not one of these elements; however, in the 1980s, General Motors found that an alloy of neodymium, iron, and boron (Nd2Fe14B) not only produces a magnet, but its crystal structure causes it to be an especially strong magnet. 

    Also called “rare-earth” magnets since neodymium is in the group of elements called rare-earths.

    Tiny yet strong

    Small little cubes, but still cool as heck when you consider everything about them. Go read up on them, it's your chance to discover!

    Powerful tiny magnets

    I bought these to use with some magnetic sand, and they work wonderfully. I drop one down a thin test tube so I can wipe off the sand easily afterward, plus it shows well against the glass. Great value for 20 of them.

    Fun magnets

    This is a neat set of neodymium magnets that I have on my desk at work, they are a minor conversation starter but are also great for implanting inside 3D prints.

    WE TAKE SCIENCE SERIOUSLY

    You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.

    We're dedicated to providing the best scientific products available—whether they're fragments of scientific importance, experimental activities, or just interesting things that scratch your curiosity itch.

    With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.

    Believe in yourself; for everything else, there's science.
