Mutual Inductance of Coaxial Tube and Coil

[QUOTE="Baluncore, post: 5959881, member: 447632"] Welcome to PF. A coil inside a conductive tube will “see” it's reflection from the inner surface of the tube. So the tube will appear to be the mirror image of the coil. The eddy currents will be the reflection. The current will be reversed in the image, so the combination becomes a differential transmission line, a transmission line transformer or a current transformer. The details of end termination (to the tube) will be critical in analysis of the transmission line model. Also, the coil current frequency spectrum, the length of the tube and the length of wire in the coil will be important. Stainless steels are not always well behaved at radio frequencies, some are magnetic, some not. What grade of stainless steel is used? [/QUOTE]
