|alternating field;[电]交变磁场
交替磁场（Alternating Magnetic Field）是指强度和方向随时间发生周期性变化的磁场。其核心特征在于磁感应强度矢量（通常用 (vec{B}) 表示）的大小和方向按照特定规律（最常见的是正弦规律）往复变化。
权威参考来源：
“alternating magnetic field”的中文译名为交变磁场，指方向与强度随时间发生周期性变化的磁场。以下是详细解释：
交变磁场通常由交流电通过线圈产生（根据安培环路定律）。当电流方向周期性变化时，磁场方向也随之改变。此外，旋转的永磁体或电磁铁也可生成交变磁场。
高强度交变磁场可能干扰电子设备或对人体产生生物效应（如电磁辐射），需遵循安全标准（如国际非电离辐射防护***（ICNIRP）的限值）。
如需进一步了解具体应用或公式推导，可参考电磁学教材或工程类文献。
