Experiment Design on Line Expansion Coefficient of Metal by Measuring Inductance
Weixi Chen · Journal of Southwest China Normal University · 2014
Coil self inductance coefficient(L)changes with the inserted depth variation of iron core,which can be changed by the coil inductance that change core length,and linear expansion coefficient obtained by the length change.This paper deals mainly with the introduction of the self inductance coefficient to measure the coil with AC Bridge,and then measuring metal linear expansion(α)coefficient of the basic principle,experiment method and experiment results.
