Used in these demonstrations

Overhead galvanometer with clear acrylic faceplate showing ±2 mA DC scale, telegraph key switch, C battery with red leads, and coil set with green primary winding and three red secondary pickup coils on a metal frame

Safety

Electromagnetic Induction

A battery-powered electromagnet core inserted into pickup coils produces galvanometer deflection only during switching transients — demonstrating that induced EMF requires changing magnetic flux (Faraday's Law). Reversing the battery leads …
