Abstract: The traditional self-induction phenomenon demonstration experiment can only be studied qualitatively in high school physics teaching.Carrying out the traditional self-induction phenomenon demonstration experiment study with DISlab can achieve a qualitative and quantitative research.Through the experiment circuit improvement,the effect of experimental demonstration is further enhanced.During the experiment,we find some special phenomena and thinking them deeply.As in the current,a peak is appeared before the voltage stability in the light bulb,and when changing the polarity to repeat the experiment,the relaxation time becomes long,etc.

Key words: DISlab, self-induction, current, voltage
