Dependence of Demagnetization Quality of Ferromagnetic Bodies on Frequency Relationship and Duration of Demagnetization Process

Abstract

Experiments have revealed that demagnetization quality of ferromagnetic bodies depends on characteristics of demagnetizing field that are determined by their size and internal properties. Every ferromagnetic body with a specific size and internal properties has its frequency and time period of demagnetization when a residual demagnetization will be a minimum one.
