• The magnetic flux of a pair of Helmholtz coils is to be determined and plotted graphically as a function of the coil current. The Helmholtz system calibration factor is calculated from the slope of the line.
• The horizontal component of the earth-magnetic field is determined through superimposition of the Helmholtz field.
• The angle of inclination must be determined in order to calculate the vertical component of the earth-magnetic field.
