Magnetic field measurement is important for the study of space plasmas, where an intensive electromagnetic activity occurs. The full knowledge of electromagnetic waves needs in situ measurements of electric and magnetic components, coupled differently from free space below plasma frequency. The latter approches 20MHz in the vicinity of Earth and 100MHz at one solar radius. In up-today geophysical space missions, magnetic sensors measured fields from DC to 1MHz, with a 1 fT Hz magnetic noise density between 10kHz and 1MHz. Measurement near the Sun necessitates a magnetometer extending these performances to higher frequencies, 100MHz at best. We design a sensor in the 10kHz-100MHz band, with the same noise level, to satisfy the scientific nee...
