Superior version of the classic device for investigating electromagnetic induction. Primary and secondary coils are wound on robust molded formers fitted with shielded banana jacks. The plated iron core has a molded handle for accurate positioning in the coils. The primary coil has 175 turns of 18 AWG insulated copper wire (diameter 34mm, length 100mm, resistance 0.43 Ω, self-inductance ≈3.1mH). Secondary coil has three available windings with 500, 1000, and 1500 turns of 26 AWG insulated copper wire (diameter 52mm, length 102mm, resistances 11.5 Ω, 23.3 Ω, 35.7 Ω self-inductances; 490mH, 1.97H, 4.43H). Plated iron core is 19mm in diameter and 165mm long (including handle). Includes activity guide.
