|susceptiveness;[電磁]磁化率
磁滞率（magnetic susceptibility）是描述物質在外磁場中磁化能力的物理量，定義為磁化強度( M )與外加磁場強度( H )的比值，用公式表示為： $$ chi = frac{M}{H} $$ 其單位為無量綱量，屬于二階張量。根據數值的正負，物質可分為：
該參數在材料科學和工程領域有重要應用，例如：
測量方法包含振動樣品磁強計（VSM）和超導量子幹涉儀（SQUID），精度可達(10^{-8})emu量級。現代研究顯示，納米材料的表面效應會顯著改變其磁滞率特性。

magnetic susceptibility（磁化率）是電磁學中描述物質在外磁場中被磁化程度的物理量，通常用符號 $chi$ 表示。以下是詳細解釋：
基本定義：磁化率表示物質的磁化強度（$M$，單位體積的磁偶極矩）與磁場強度（$H$）的比值，即： $$chi = frac{M}{H}$$ 這表明物質在外磁場中的磁化響應能力。
國際單位制中的擴展：結合磁感應強度（$B$）與磁場強度（$H$）的關系： $$B = mu_0 (H + M) = mu_0 (1+chi)H = mu H$$ 其中 $mu_0$ 是真空磁導率，$mu$ 是物質的磁導率，$mu = mu_0 (1+chi)$。
總結來說，磁化率是物質對外部磁場響應能力的量化指标，廣泛應用于物理學、工程學和地球科學等領域。
