All atoms consist of a positively charged nucleus and many electrons moving around it. The directional movement of electrons forms an electric current, such as that in a metal wire. Using electric and magnetic fields, the movement of electrons (in solid and vacuum) can be controlled according to needs, so as to manufacture various electronic instruments and components, such as various electron tubes and electron microscopes. The crystal diffraction experiment in 1927 confirmed the fluctuation of electrons.
