Fluxgate Magnetometer (MGF)
The Fluxgate Magnetometer onboard Mio (MGF) measures the magnetic field to study various magnetospheric processes (such as magnetic reconnection, field-aligned currents etc.) in Mercury’s magnetosphere, physics of bowshock and magnetosheath, also magnetic field properties in the inner-heliosphere. It consists of two tir-axial fluxgate magnetometers and power supply units. The magnetometer is able to observe the magnetic field with a vector rate of maximum 128 Hz.
