[@Hot-Introduction]

This is the best demonstration which I could find on the internet.

Nice demo!

Thanks Grady! I really liked your video on static stability. Nothing like spending dozens of hours making something for a 10 sec demo... also, watch out for the cat!

Many displacement transducers are made using this principle. Are used in automotive construction industry, even the hard drive platters are measured with such transducers. They have very high resolution up to 0.1 um .

From where i can get that ferromagnetic core??..

This should do the trick: www.alibaba.com/product-detail/R4X12-High-Permeability-NiZn-Ferrite-Rod_60263210228.html MnZn ferrite rods probably would be even better than NiZn rods for this type of application. (for posterity)
