摘　　要：根据电磁感应原理,推导出电磁炉外泄电磁辐射中感生电场、磁场的幅值与测试电感线圈中产生的感生电动势有效值的关系,阐述了应用电感线圈、交流毫伏表和示波器测试电磁炉在周围空间产生的电磁场频率和周围空间中不同方位、不同距离的电磁场大小的方法和过程。同时还测试了不同工作状态下电磁炉最大外泄电磁辐射情况和使用不同大小的锅具时电磁炉最大外泄电磁辐射情况。The paper presents the relations among induced electromotive force, magnetic amplitude and testing electromagnetic inductive choke in induction cooker＇s leakage of electromagnetic radiation based on electromagnetic induction principle, and elucidates electromagnetic field frequency around the cooker with electromagnetic inductive choke, AC Millivoltmeter and oscilloscope and testing methods and process for the electromagnetic field values in different directions and distances. Meanwhile, cooker＇s maxim electromagnetic leakages in different working states and using different sizes of cookers are tested.
