Abstract: 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.

Key words: electromagnetic induction, skin effect, electromagnetic field, common mode interference
