Product Code : SCL-PLE-11589
The JLab India Ring Launcher (Elihu Thomson’s Apparatus) is a high-impact laboratory instrument designed for the empirical study of electromagnetism, induced eddy currents, and Lenz's Law. Optimized for Secondary and University-level Physics laboratories, it provides a dramatic physical demonstration of magnetic repulsion between a current-carrying solenoid and a conductive ring. Durable system ensures standardized instructional delivery for electromagnetics, induction, and AC circuit modules.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Induction Interface -> Facilitates student visualization of how a primary AC magnetic field induces a secondary current in a nearby conductor, supporting Electromagnetism Module 101 (Understanding).
- Lenz's Law Verification -> Enables the physical study of magnetic opposition; the ring is propelled because its induced magnetic field opposes the solenoid's changing field (Applying).
- Eddy Current Connectivity Analysis -> Supports the Analysis of why a solid aluminium ring launches while a split ring or plastic ring remains stationary, highlighting the need for a continuous conductive path.
- Trajectory & Force Evaluation -> Allows students to Evaluate the impact of launch angle, initial current (speed), and air resistance on the ring’s flight path and height (Evaluating).
