| This is a degree of sensitiveness that cannot be obtained with any of the astatic instruments known up to the present. |
| Fig. 139 shows how a current can be generated by two coils, H being connected to an astatic galvanoscope and E to a battery. |
| As the reactor embodies astatic behaviour, it is not possible to compute the matrices in a chosen operating point. |
| Note in which direction the right-hand end of the astatic needle is deflected. |
| Fig. 67 shows an astatic galvanometer for measuring weak currents. |
| Based on the results, we show which types of astatic ponds are most exposed to contamination and suggest some conservation practices that may reduce the influx of heavy metals. |
