The determination of geomagnetic polarities in volcanic sequences was carried out in the field using portable fluxgate magnetometers. |
Spinner magnetometers utilize the rotating moment of the specimen to alter the current in a nearby fluxgate pick-up coil, of cylindrical or ring design. |
Recording magnetometers flown over large areas could distinguish rapidly between magnetic and non-magnetic rock groups. |
As he travelled, he set up instruments called magnetometers to measure electric currents in the upper atmosphere. |
Well, what we actually do is plant what we call electrodes which are little electrical sensors and magnetometers which sense the magnetic fields. |
The software performs numerous quality checks on the data, and on the correct operation of the magnetometers. |
