I recently bought 5 Torroid core on ebay (**broken link removed**)
after it arrived I went to site - https://coil32.net/online-calculators/ferrite-torroid-calculator.html to calculate the permeability.
I measured the green core using a vernier . Then i wound swg25 (0.5mm) wire on it (18 turns) and measured inductance. it read 2.38mh. I adjusted the permeability value to get the inductance 2.38 mh(at coil32 site). I ended up getting a u=9000(relative magnetic permeability). Is it really possible to get a value of 9000?
I also checked the value of an old inducctor with given valueu of 100uh., for me it read 104uh.
