The LEMI-151 search-coil magnetometer is intended for measurements of 3 components of AC magnetic field vector. It is a new design specifically developed for the SEAM space mission to achieve optimal performance within the volume constraints. As the result a miniature search-coil magnetometer with best combination of parameters was created and tested. Its parameters and external view are given below.
