This demonstration induction coil consists of a primary coil wound from enameled copper wire (approximately 0.5 ohms resistance, 110 x 30 mm) and a secondary coil of fine enameled copper wire (approximately 100 ohms, 120 x 82 mm) that fits over the primary. A cylindrical iron core measuring 160 mm long and 15 mm in diameter slides through both coils. Both coils are fitted with 4 mm terminals for banana-plug connections. The apparatus is RoHS-compliant and is designed for demonstrating electromagnetic induction principles in the physics classroom.
