Hi SB,
remember, that the target inductivity is dependent on:
- shape of target
- orientation of target
- target position to the TX coil
TX magnetic fields aren't uniform and their direction changes on position of the target to the TX coil. The induced eddy current path changes due to this fact. (Note, eddy current path = coil winding geometry). Well, the coil coupling coefficient between TX and target changes as well.
The corresponding target time constant tau = L/R changes.
When will you give up the discrimination?
