MAG












    The dual vector fluxgate magnetometer (MAG) has two tri-axial fluxgate sensors, one mounted at the outer edge of a solar array, to provide functional redundancy and to allow the identification of magnetic fields generated by the spacecraft. MAG operates over a large dynamic range of ~ 60,000 nT with resolution 0.05 nT.

    Measurement Objectives

    MAG measures the intensity and direction of the magnetic field in all regions traversed by the spacecraft. The instrument sensitivity will measure the vector magnetic field in the unperturbed solar wind (B~3 nT), the magnetosheath (B~10-50 nT) and crustal magnetospheres (B<3000 nT). MAG has the ability to spatially resolve crustal magnetic cusps (horizontal length scales of ~100 km). In combination with other instrument, MAG will:
    • Determine the morphology of the ionosphere and magnetosheath (with LPW and SWEA)
    • Determine the structure and topology of the magnetic cusp regions (with SWEA)
    • Determine the convection electric field (with SWIA)
