... laminated copper is a poor medium to conduct B-fields through. That means the value is much closer to unity than half. Plus, the larger the coil the more magnetic shielding & the greater still is the mutual impedance. Given the MG1.6/QR 3.5mH coil's enormity, we're talking around 95% which is about the 5% tolerance of the coil.» moderate Mart £ « Planar Asylum
