magnetic transducer

magnetic transducer

[mag′ned·ik tranz′dü·sər]
(electromagnetism)
A device for transforming mechanical into electrical energy, which consists of a magnetic field including a variable-reluctance path and a coil surrounding all or a part of this path, so that variation in reluctance leads to a variation in the magnetic flux through the coil and a corresponding induced emf (electromotive force).

On the basis magneticreactive effect the theoretical fundamentalses and methods of build-up of magnetic transducers are designed which take into account influence of a magnetic field to allocation of density of injected carriers of charge in the basis of bipolar and channel field-effect transistors, which diagrammatize transducers.
In addition, the system employs four magnetic transducers mounted directly on the track, two to monitor train speed and two to monitor direction.
