Footonitest koosnev aine (OK, "ainult" kolmest footonist koosnevad osakesed), millel on ka seisumass? _________________ Tee inimesele lõke ja tal on soe üheks päevaks, pista ta põlema ja tal on soe elu lõpuni. (Terry Pratchett)

Lifts usually move with the help of engines in which rare earths from China are stuck. The medium-sized company Ziehl-Abegg has found a different solution.
...
The motor, which is to go into production in the second half of the year, also works with permanent magnets, but on the basis of hard magnetic ferrite, i.e. an iron oxide, to which a pinch of further substances is usually added. “There’s nothing in it from China,” a spokesperson said. Actually, it is a known construction, which has the disadvantage that the rotor is significantly longer than one of neodymium connections. The engine, says Ziehl-Abegg, however, has the same torque with unchanged dimensions.
