Determining the RMS time derivative of the magnetic field
strength is accomplished by simply dividing the indicated RMS
magnetic field strength by the shortest transition time obtained
from the oscilloscope measurement procedure.
The waveform of the electric field obtained from the same VDT is
shown for comparison in Figure 14.

as used in Figure 13 observed with an oscilloscope
connected to the preamplifier output jack.
