Topic: How to read Inductance from a bobine  (Read 111 times) previous topic - next topic


The circuit may work, but the inductance of wire  wound on a ferromagnetic core depends on the core material characteristics and the physical design as well as the number of turns of wire.



Note that for some magnetic materials (actually all of them) the inductance (and loss) varies with frequency, so
inductance is best measured at a fixed frequency(*), not by resonating with a fixed capacitance.  However this
is harder to do without more complex test equipment.

(*) If you want meaningful comparisons between different materials.
