Abstract
The present paper aims to develop the performance of the triboelectric nanogenerator (TENG) based on triboelectrification and magnetic field. PMMA sheet was inserted under the triboelectrified area to permit the lines of magnetic field to flow from one pole of the magnet to the other with the same intensity. Besides, steel sheets of different thickness were replaced the PMMA sheet to investigate their effect on the generated voltage.
 
The present experiments revealed that the proper position of the permanent magnet was to be above the steel sheet closer to the friction surface. The steel sheet redirected the lines of flux of the permanent magnet and distributed the magnetic field on the friction surface providing an extra magnetic field superimposed on the field supplied by the permanent magnet. Added to the magnetic field, an electric field was generated by ESC. All those magnetic and electric fields are responsible for the increase of the voltage. Voltage significantly increased with increasing the steel thickness for contact-separation and sliding. The steel sheet represents an extra magnet. It redirects the lines of flux into easier path into the friction surface. It seems that the steel sheet concentrates the field lines on the friction surface, where thick steel sheet can hold higher magnetic flux than thin sheets.
