|alternating field;[電]交變磁場
交替磁場(Alternating Magnetic Field)是指強度和方向隨時間發生周期性變化的磁場。其核心特征在于磁感應強度矢量(通常用 (vec{B}) 表示)的大小和方向按照特定規律(最常見的是正弦規律)往複變化。
權威參考來源:
“alternating magnetic field”的中文譯名為交變磁場,指方向與強度隨時間發生周期性變化的磁場。以下是詳細解釋:
交變磁場通常由交流電通過線圈産生(根據安培環路定律)。當電流方向周期性變化時,磁場方向也隨之改變。此外,旋轉的永磁體或電磁鐵也可生成交變磁場。
高強度交變磁場可能幹擾電子設備或對人體産生生物效應(如電磁輻射),需遵循安全标準(如國際非電離輻射防護***(ICNIRP)的限值)。
如需進一步了解具體應用或公式推導,可參考電磁學教材或工程類文獻。
