Electrical Bell Science Experiments Vertical Physical Acoustic Experiment Teachi

Feature: \n 1. WORKING PRINCIPLE: Electromagnet generates magnetism when energized, sucks the armature, makes the moving and static contacts contact, and works by using the magnetic effect of electric current.\n2. WITH BASE: Physical acoustic experiment with base, make the experiment demonstration more intuitive, easier for students to observe the state of each part and learning.\n3. GOOD TEACHING TOOLS: Electrical bell science experiments teaching tools are good teaching tools for teaching physics, enhancing children's hands on ability and fun.\n4. USAGE: Vertical physical acoustic experiment is very suitable for teachers to explain the current magnetic effect related physical knowledge.\n5. DURABLE MATERIAL: Electrical bell science experiments are made of plastic and copper, not easy to be damaged, durable and can be used for a long time. \n\nSpecification: \n\nItem Type: Electrical Bell Science Experiments Vertical\nMaterial: Plastic, Copper\nWorking Volta:
