For instance, in discussing Dretske's magnetesome example she says that, "[t]he mechanisms THAT USE the magnetesome's offerings don't care at all whether the magnet points to magnetic north, geomagnetic north or, say, to the North Star.
Imagine there was a magnet pointing your knife at your opponent's knife.
In most materials these atomic magnets point in random directions, so that the material itself is not magnetic.
The whole point of Emily's moors was their wild freedom, but the signs (in Japanese and English, so great is the power of this touro-magnet) point to one tried-n-tested clough, beck and ruin.
Once enough jostling has occurred, all these miniature magnets pointed in the same direction creates a magnetic effect strong enough for us to notice.
In certain metals, atoms act like tiny bar magnets pointing in random directions.
Subsequent geological forces jumbled up the grains and left them with the magnets pointing in all directions.
Let us note, however, that all the structures that have been discussed above are collinear structures: on the average (in time) all the atomic magnets pointing in one or the opposite direction are parallel to a single direction.
With the availability of High-Temperature Superconducting (HTS) prototype cables, based on high-performance REBCO Coated Conductor (CC) tapes, new designs can now be made for large bore high-field inserts in superconducting solenoids, thus extending the magnet operating point to higher magnetic fields.
We first present some results on boiling heat transfer in helium under reduced gravity using a commercial magnet and point out the limitations in volume and magnetic force homogeneity to perform reduced gravity experiments with such a non ad hoc magnet.
