ZXYHLLGK Vertical Base DC Electric Bell Demonstration Model, Electromagnetic Intermittent Circuit Physics Teaching Instrument for Working Principle Experiments
ZXYHLLGK
This vertical electric bell model works as dedicated demonstration prop for in-class physics teaching and laboratory electromagnetic principle display to enrich physical curriculum presentation links. The demonstrator fully unfolds electric bell’s internal structure and cyclic operating mechanism, allowing direct naked-eye observation or enlarged viewing with auxiliary optical projection equipment. Equipped with refined polished metal components and solid wooden base, every part undergoes professional abrasive finishing for tight assembly and stable long-term experimental performance. If irregular vibration occurs during operation, operators can adjust the spacing between positioning screw and vibrating reed to optimize contact state and restore normal ringing performance. Connect the two terminal posts to a 4-6V DC power source and install a control press switch on the circuit; pressing the switch will produce periodic intermittent ringing to restore real electric bell working state.
