The paper aims to construct a device, using the tech of maglev, to weigh things and behave artistically. Design an adsorption of magnetic electronic scale, which is based on the related electronic scale design researches. The paper introduces the system structure of the magnetic electronic scale and implementation methods, and focuses on the non-linear feature of the electromagnetic coil, electromagnetic force system model and the control model. During the design we solved several difficulties: the nonlinear feature of the electromagnetic field, the mathematical model of the system, the selection of various materials and components in machine, and the design of control circuit and debug parameters. There are several innovations: First, we use infrared sensor and also try camera as the sensor;second, we use image as feedback, cooperating with NI and Labview; third, we construct our coil with 1j-50 Fe-Ni soft magnetic alloy.
