| Abstract: | The electron charge-mass ratio testing instrument have been used,with the compass,gradienter and plumb and other simple tools,to measure the forward and reverse excitation current after magnetic focusing.The horizontal and vertical components of the earth’s magnetic field have been computed,in order to determine the magnitude and direction of the geomagnetic field. |
