Uses of Neodymium Magnets
Nickel plated neodymium magnet on a bracket from a hard drive.
The magnets in your possession are some of the most powerful magnets in the world. They are made out of a neodymium-iron-boron material, or Nd2Fe14B, of which iron is the main component. Their field strength has been measured at 12.5 kiloGauss, or 1.25 Tesla (tens of thousands of times stronger than the earth’s magnetic field). Their incredible strength makes them a constant source of wonder as well as ideal demonstrators of the force of magnetism in traditional, and some not so traditional, experiments. As you may already know, these are not ordinary magnets and cannot be handled as such.
Here is just some of the uses that neodymium magnets have been put to:
Repairing my fridge seal. Put a couple inside the plastic of the seal and it holds the door shut beautifully
