Primary and Secondary Coils, For investigating electromagnetic induction., Each

Details

Here is the corrected text: This superior version of the classic device for investigating electromagnetic induction features primary and secondary coils wound on robust molded formers fitted with shielded banana jacks. The plated iron core, which measures 19mm in diameter and 165mm in length (including handle), has a molded handle for accurate positioning within the coils. The primary coil consists of 175 turns of 18 AWG insulated copper wire, with a diameter of 34mm, a length of 100mm, a resistance of 0.43 ohms, and a self-inductance of approximately 3.1 millihenries. The secondary coil offers three available windings, featuring 500, 1000, and 1500 turns of 26 AWG insulated copper wire (a feature not typically found on competing products). The secondary coil's specifications include a diameter of 52mm, a length of 102mm, resistances of 11.5 ohms, 23.3 ohms, and 35.7 ohms, and self-inductances of approximately 490 millihenries, 1.97 henries, and 4.43 henries. This product includes an activity guide.
