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. (Usually only one available
windings on competing products) (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.
Dimensions: 4" x 2.75" x 6.75".
