摘      要：An Fe73.5Cu1Nb3Si13.5B9 nanocrystalline toroidal core made by isothermal furnace annealing shows good thermal stability of magnetic properties and excellent soft magnetic properties due to the full release of the internal stresses of the core during the annealing *** on the feature of the magnetic core,a novel non-contact type weak current sensor adopting single nanocrystalline core and double-winding excited by multivibrator bridge is *** measuring principles for static current are given in theory by an established mathematical model of the *** theory is in good agreement with the experimental results and it indicated clearly the key factors affecting performance parameters for the *** multivibrator bridge output signal was analyzed by Fourier ***,according to the theoretical results,the method to design the signal conditioning circuit was introduced.
