Field induced magnetization issues on spacecraft magnetic cleanlines

The disturbance magnetic field produced by a spacecraft affects the measurements being used to detect the geological characteristics of planets or to understand plasma-dynamics in space. Thus, magnetic cleanliness is an increasingly important issue for spacecraft design. Magnetic cleanliness involves control of remanent magnetized parts, control of field induced magnetization and control of current produced magnetization. Methods to control remanent magnetized material have a long history in spacecraft design. Methods to control current produced fields are closely related to classical EMC, whereas methods to control field induced magnetizations are comparatively rare. Therefore, this paper deals with methods applicable for the control of field induced magnetization.
