【 摘 要 】

The article describes the use of piecewise-polynomial approximation and approximation in the form of a power polynomial to the dynamic characteristics of the magnetization. The feasibility of this approach consists in the reduction of the amount of data used to describe the characteristics. For clarity, only the ascending branch of the dynamic characteristics of the magnetization was used. The error, arisen during approximation of the characteristic which according to the results of experimental studies did not exceed the required 5%, was estimated. As a result of the studies, it is possible to conclude about the appropriateness of approximating expressions application to describe the dynamic characteristics of the magnetization. Approximation defined as a power polynomial with the same error allows fewer approximating coefficients.
