Part 2/4:
The experiment utilizes a feret rod measuring 7.5 inches in length with a diameter of 3/8 inches. The researcher notes that this specific size works best in their current configuration. The coil length has been measured at 10 inches, and two identical coils are wound to a combined length of 20 inches, positioning the feret rod optimally within the coil assembly.
Interestingly, the optimal performance is observed when the feret rod is inserted exactly halfway into the coil, with an insertion depth of about 3 and 5/8 inches. This precise placement appears to maximize the efficiency of energy transfer or electromagnetic induction, highlighting the importance of meticulous setup in such experiments.
