Abstract
The application relates to the technical field of magnetic writing, and solves the problems of poor holding stability and insufficient operation flexibility of a rectangular parallelepiped structure of an eraser in the prior art. The application provides an electronic eraser and a magnetic writing device. The electronic eraser comprises an erasing component, a handle and a control circuit, wherein the erasing component is in a strip structure, the erasing component is internally provided with an electromagnet and a magnetic pole driving circuit for controlling magnetic poles of the electromagnet; the handle is in a strip structure, one end of the handle is connected with the erasing component; the control circuit comprises a key module, a power module and a motor driving module; the motor driving module continuously switches the current direction of the magnetic pole driving circuit, switches the magnetic poles of the electromagnet, and realizes erasing of handwriting on a magnetic writing board. The electronic eraser can effectively improve the stability and flexibility during use of the eraser, and improve the user experience.
