本文讨论了一种利用磁悬浮系统进行重量测量的新方法。该实验已经进行，使得它悬浮在离电磁铁固定距离处的铁磁物体，并且在物体悬浮的瞬间测量通过线圈的电流。本文提出了一种求出物体重量与相应电流之间关系的方法，可用于确定悬浮物体的重量。借助于本文确定的关系式，可以通过确定电磁铁的电流来计算未知物体的重量。
This paper discusses a new approach of weight measurement using magnetic levitation system. The experiment has been performed such that it levitates a ferromagnetic object at a fixed distance from the electromagnet and the current through the coil is measured at the instant the object is being levitated. This paper shows an approach to find out the relation between the weight of the object and its corresponding current, which can be used to determine the weight of the levitated object. With the help of the relationship determined in this paper, it is possible to calculate the weight of an unknown object by determining the current drawn by the electromagnet.
