This electromagnetic bell and relay physics kit provides a clear, handson way to demonstrate basic electromagnetism principles. Compact and durable, it is designed for classroom demonstrations, individual study, and STEM projects. Key benefits Clear visualization of electromagnetism: Shows a working electromagnetic relay and bell mechanism so students can see how current, magnetism, and motion interact. Handson learning: A DIY experimental kit that encourages active exploration and helps reinforce theoretical concepts through observation and practice. Compact and easy to handle: Base measures 156 mm x 105 mm x 100 mm (6.14 x 4.13 x 3.94 inches), making it easy for teachers and students to position on a desk and view all components. Durable materials: Constructed from PP plastic and metal for reliable performance during repeated classroom use. Versatile educational tool: Suitable for middle school physics experiments, lesson demonstrations, afterschool STEM activities, and as a practical science gift. Features and specifications Function: Electromagnetic relay and electric bell demonstration instrument for physics education. Size: 156 mm x 105 mm x 100 mm (6.14 x 4.13 x 3.94 inches). Material: PP plastic and metal. Package includes: 1 x Electric Science Experiments Kit. Note: Manual measurement may result in slight size variations of 1 to 2 cm. Typical use scenarios Classroom demonstration: Use during lessons on electromagnetism to give students a visible, working example that complements textbook explanations. Home STEM project: Ideal for middle school students to explore principles at home while building confidence in scientific observation and experimentation. Science fair or lab display: Provides a compact, functional exhibit to illustrate relay operation and electromagnetic principles. This kit is a practical, easy to use teaching aid that helps bridge the gap between theory and realworld behavior in basic electrical and magnetic systems.
