09   clock in electromagnetic field

The experiments testing how magnetic fields affects clocks
    Experiments had already proved that the difference of space in different direction is caused by geomagnetic fields. However, does the magnetic fields real affect clocks? How does it affect the clock any law?
    Somebody proffer, since the revolving bar is rotating in the magnetic fields, it will generate emf and influence the transmission of the signal. However, the magnetic lines on the surface of the earth are almost level and these types of revolution can't generate emf. More safe to say, Suppose that magnetic lines are not level. Then since the two arms are same length and movement in opposite directions, the emf from the two arms are equal with opposite directions. So, they would counteract with each other. And the said of induction emf can't explain the difference.
   We made a small coil showed in the Fig. 9.01 to test the effect of magnetic fields. We let the coil to cover one of the clocks. The current of the coils is controled in order to get 2.56GS constant magnetic fields. Then make the coil turn slowly by a stepper motor, it need 12 minutes that the coil turns cycle. We can regard the field as a still one because the rotational speed is very low. The Fig. 9.02 shows the results of the experiments which the coil runs one cycle round the X-axis, Y-axis and Z-axis of the clock.

Fig. 9.02 the data of experiment that the magnetic fields rotates round X, Y and Z axes

   We can find when the direction of magnetic fields is changed, the effect is obviou on the clocks. The magnetic fields strength of 2.56GS caused change about 11021, there is a proportional relation with the result that caused by the geomagnetic fields of 0.5GS.

    

   Therefore, The root reason which caused the clocks' differences is that the change of the magnetic fields direction, it causes the frequency of clock change.
   The farther experiments indicate that electric field can also affect clocks. But electric field experiments are rough for the countercheck of the metallic encapsulation. Here, we won't give experimental data. This effect need to be tested in a vacuum.
Continual experiments in zero magnetic fields
    We repeated the experiment in zero magnetic fields on February 2007. Eexperiment was finished in five days, collect data from zero o'clock and twelve o'clock every day. The following is  space-parameter of east west direction.

Fig. 9.03 the space-parameter of series-3 in five days (blue black lines)

    In the Fig. 9.03, the pink lines are the theoretical expected curve, the peak-to-peak value is 53. The actual curve show the blue black, without a rule between the big and the small ones or the similar trends, These two kinds of curve are much different. The results of different seasons are consistent.
