But the above phenomena was not very successful. I dont know if I am doing something wrong. I applied a range of freq(100Hz to 300Khz) and tried changing amplitude but nothing happens on the scope. Also does the reluctance value of the coil affect the eddy current response.
The multilayered coil will probably have a smaller magnetic path (length)

The low value of pull-up resistor is probably loading down the inductor so much that it doesn't produce any significant change. I suggest using the inductor in combination with a capacitor as an LC oscillator, and as Brevor suggested, measure the frequency shift.Hi, Thanks for your reply. I really appreciate it.
My inductor is connected in series with a pull up resistor of very low value and the circuit is powered by a voltage source of set frequency. I presumed that the frequency cannot change since it is determined by the source. Would you be able to know if the coil was part of an oscillator circuit? I am also unsure if the reluctance of the inductor will have a MAJOR influence on the amplitude or frequency response.
Yes the coil was in the LC network of a colpitts oscillator circuit.Would you be able to know if the coil was part of an oscillator circuit? I am also unsure if the reluctance of the inductor will have a MAJOR influence on the amplitude or frequency response.
