Iron Nail Bridge - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Operating instructions: 1. Press the "power on" button to start the timer; 2. Connect the left and right "bridge piers" with small iron nails within the specified time and build the "bridge deck"; 3. Press the 'power off' button and observe the phenomenon. Function Overview: Exhibition items consist of a bridge pier made of two electromagnets and several iron nails. The experiencer presses the power button, and the digital display starts counting down. The experiencer needs to use iron nails to complete the overlapping of the bridge deck within the set time. When the time is up, the electromagnet will automatically power off, or the electromagnet can be directly turned off by pressing the power off button. The exhibition items illustrate the principle of electromagnetic conversion by magnetizing iron nails and arranging them in a "bridge" shape through the magnetic field generated by an energized coil. Exhibition items mainly consist of a platform, coil device, delay device, etc. The iron nail bridge exhibition items consist of two sets of electrified coil devices placed parallel to each other, with multiple iron nails placed in the nail slots between the coils. The audience presses the button to power on the coil, and both coils will generate a magnetic field. Due to the ability of magnets to magnetize iron, viewers can connect iron nails one by one to the inside of two energized coils, forming an iron nail bridge.
