Product overview This square coil assembly is designed for teaching and laboratory use. The unit is made from wound wire, coil formers, and wiring forks to provide a reliable, easytohandle demonstration tool for electromagnetic phenomena. Key benefits Clear demonstrations: Built to show the Oersted effect, magnetic field patterns, and electromagnetic induction in a way that is visible and repeatable for students. Ready for classroom use: Simple connections through wiring forks make setup fast, reducing time spent on assembly so teachers can focus on the experiment. Durable construction: materials and fine craftsmanship provide consistent performance during repeated use in lessons and lab sessions. Protects experimental integrity: Robust design reduces variability in results when handled correctly. Primary functions and attributes Function: Demonstrates interaction between electric current and magnetic field and the principles of electromagnetic induction. Construction: Square coil composed of wires, coil formers, and wiring forks for secure electrical connections. Performance: Stable coil geometry and solid wiring forks help maintain consistent magnetic field geometry and repeatable measurements. Compatibility: Intended for middle school and secondary school physics curricula and school laboratory equipment collections. Use scenarios Classroom demonstration: Use with a DC power source to show the Oersted experiment and the direction of the magnetic field around a currentcarrying conductor. Laboratory experiment: Integrate with sensors or galvanometers to investigate electromagnetic induction when the current changes or when the coil is moved relative to a magnetic field. Science displays and teaching collections: Serve as a handson exhibit for student projects, science fairs, or as part of a teaching materials inventory. Care and handling Do not hit or press hard on the instrument. Mechanical shock or deformation can alter the coil geometry and affect experimental results. Handle wiring forks and connections gently to preserve the contact surfaces and maintain reliable electrical connections. Store in a dry, secure location to avoid accidental damage. Practical advantages for teachers and labs Supports standard middle school physics experiments without complex assembly. Reduces preparation time and helps students observe fundamental electromagnetic principles directly. Useful as a teaching aid, reusable lab component, and educational display piece.
