Product overview A classroom demonstration kit that illustrates the magnetic effect of electric current through a compact, vertical setup. The kit mounts on a base so all components remain visible and easy to observe while illustrating how an electromagnet can convert electrical energy into mechanical motion and sound. Key features and functions Clear demonstration of principle: When the electromagnet is energized, it becomes magnetic and attracts the armature, closing the moving and static contacts to complete the circuit and show electromechanical conversion. Audible feedback: When powered, the electromagnet pulls the reed toward the magnet and a hammer strikes the iron piece to produce a clear sound, reinforcing the action students observe. Visible components: The vertical base holds the electromagnet, reed, hammer, moving plate, and static plate in plain view so students can follow current flow and component motion. Power compatibility: Designed for use with a DC 3 to 6 volt power supply. Simple operation: Connect to an appropriate DC power source to energize the electromagnet and demonstrate the sequence of attraction, contact closure, and circuit completion. Benefits for teachers and students Makes abstract concepts tangible by showing realtime actions of electromagnetism and contact switching. Facilitates classroom explanation of circuit loops, moving versus static contacts, and energy conversion without complex setup. Enhances retention through combined visual and auditory cues. Typical use scenarios school physics lab demonstration of the magnetic effect of current and basic electromechanical switching. Teacherled classroom activity to show how electromagnets operate and how moving contacts complete a circuit. Handson station for small groups to observe component motion and discuss current flow and mechanical response. Specifications and practical notes Operational voltage: DC 3 to 6 V. Form factor: Vertical mounting on a base for straightforward observation. Main components: Electromagnet, armature/reed, hammer, iron striker, moving plate, static plate, and base. Safety and setup: Use a suitable DC power supply within the specified voltage range and secure the unit on a desk or bench before operation. This kit is intended for educational demonstrations of electromagnetic principles and electromechanical switching in classroom and laboratory settings.
