Principle
A constant magnetic field, its magnitude and direction known, is superimposed on the unknown earth magnetic field. The earth-magnetic field can then be calculated from the magnitude and direction of the resulting flux density.
Tasks
1.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.
2.The horizontal component of the earth-magnetic field is determined through superimposition of the Helmholtz field.
3.The angle of inclination must be determined in order to calculate the vertical component of the earth-magnetic field.
