What are the Principles on which inductive transducer work?

Inductive transducers operate on the principle of electromagnetic induction, where a change in magnetic flux induces an electromotive force (EMF) in a coil. They typically consist of a coil and a ferromagnetic core, where the movement or variation of the core affects the inductance of the coil. As the inductance changes due to displacement or other physical parameters, it produces a corresponding change in the output voltage, which can be measured and converted to represent the desired variable. This principle allows inductive transducers to effectively convert mechanical motion into electrical signals.
