The discovery of Professor oersted was limited to the action of the electric current on needles previously 192 magnetised. |
Thus needles not only degauss, but also are magnetised in an opposite direction. |
Consistently in almost every item, notably in Schubert's Unfinished, Brahms's Second or Bruckner's Eighth Symphonies, there is an incandescent glow that has one magnetised. |
When the amplifier is switched on, all the tuning-forks are magnetised, and become electro-magnets. |
From protozoa or Protista to plants and animals the graduation is closer than from magnetised iron to vitalised sarcode. |
One is that the magnetic sensors are grains of magnetite, a form of iron oxide which, as its name suggests, is easily magnetised. |
