Magnetic Nano
A magnetic nano (often shortened to just nano) is a small metal container, measuring a centimetre in height and width, with a screw thread, screw-top lid and a thin, cylindrical magnet at its base. They often have an O-ring seal between the lid and the body to make them easier to open and partially waterproof. Original use Magnetic nanos were originally manufactured in 2001 to store flashing LED lights for use as jewellery, giving them the colloquial name 'blinkies'. The LED went inside the lid, with two button cell, button batteries inside the nano's tube and a rare-earth magnet at the base, so the nano could attach to clothing and jewellery. Use as geocache containers When it was discovered that magnetic nanos can be used as Geocaching, geocache containers, they were quickly mass-produced and sold for that purpose. They are widely known in the geocaching community as one of the smallest geocache containers. Magnetic nano geocaches only contain a thin, rolled-up paper ...

Magnetism is the class of physical attributes that are mediated by a magnetic field, which refers to the capacity to induce attractive and repulsive phenomena in other entities. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomena of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetization, magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples. The prefix ' refers to iron because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4. All substances exhibit ...
