High frequency electrical wire electromagnetic induction and experimental study of skin effect series

设计一组通电导体间电磁感应及趋肤效应实验,可观测通电导线间和同轴电缆线的共模干扰现象;利用自制的高频电磁感应综合实验仪观测高频载流导线的趋肤效应,并利用串联谐振测量因趋肤效应引起的良导体损耗电阻随频率增大的特性,证实趋肤效应是由电磁感应现象引起的,并对电磁感应能量无线传输进行验证,上述系列实验有利加深对电磁感应原理及作用的理解.

A set of electromagnetic induction and skin effect experiments on the electrical wire are designed,which can be used to observe the phenomenon of common mode interference of electrified wire and coaxial cable.The high frequency electromagnetic induction apparatus of current carrying conductor skin effect is observed by self-made high frequency comprehensive experimental instrument,and a series resonance is used to measure the increase of good conductor loss resistance with increasing frequency,which is induced by the skin effect.It can be further confirmed that the electromagnetic induction phenomenon can give rise to the skin effect.Meanwhile,we also verify the energy radio transmission of electromagnetic induction,the series of experiments mentioned above should give us better understanding of the principle and effect of electromagnetic induction.
