摘要
阐述检测物体是否产生了电场的方法;通过实际检测证实立方体永磁体既产生了负静电场,也产生了正静电场,并测定了具体的场强.
The method of testing whether the electric field is generated is introduced. In experimental test, not only the negative static electric field, but also the positive staticelectric field are generated in cubic permanent magnet, and the field strength is measured.
