用力敏传感器测量真空磁导率

摘要

In this text, there is a conductor with current in a magnetic field which produced by an illimitable conductor with current. Thus the conductor with current is forced by the magnetic field. Then transmuting the force into voltage by the pressure transducer, measuring the magnetic force by observing the change of the pressure transducer, thereby, the permeability of vacuum is measured indirectly.%用可以看作无限长的通电长直导线产生磁场,将载流导体放入该磁场中.此时载流导体将受到无限长通电导线产生的磁场的作用,用力敏传感器将该磁场力转化为电压,观察力敏传感器示数的变化并测量出磁场力的大小,从而间接测量出了真空磁导率.
