The purpose of this investigation is to study the interplanetary and induced cometary magnetic fields before and during the encounter with Comet Halley. The instrument consists of a main triaxial fluxgate magnetometer system mounted on top of a tripod on the spacecraft. In a 12-bit analog-to-digital conversion the dynamical ranges are plus and minus 16, 64, 256, 1024, 4096, 16384, and 65536 nT with automatic range switching. An inner biaxial magnetometer system is used for correcting the spacecraft magnetic field. During the encounter the sampling rate will be approximately 28 vectors per second, while the spacecraft spin rate is 15 rpm.
