series of complex coefficients obtained by the expansion in a Fourier series of the AC magnetization M(t)
Note 1 to entry: The AC magnetization, M(t) , under the magnetic field strength of h0cosωt is expanded as: M(t)=h0∞∑n=0[κn'
where
and
are the real and imaginary parts of the AC magnetic susceptibility for the order . Note 2 to entry: The fundamental components
and
are mostly observed for measurements of superconducting transition. Note 3 to entry: The AC energy loss density is given as: .
Note 4 to entry: This entry was numbered 815-17-13 in IEC 60050-815:2015.
