Magnetovalve (magnetic circuit) - definition
A Magnetowire is a structural element made of ferromagnetic material to direct magnetic flux in a specific path, analogous to the role played by conductor in electrical circuits. Its function is to concentrate and direct the magnetic field lines so that magnetic energy can be efficiently transferred between different parts of the system, with minimal losses and field dispersion.
Magnetowires are commonly used in electromagnetic devices such as transformers, electric motors, induction coils and solenoids. Thanks to the high magnetic permeability of the ferromagnetic materials from which they are made, they enable strong magnetic coupling and increased induction in the cores without the need for high currents. The shape and geometry of the magneto coil have a significant impact on the field distribution, its uniformity and the efficiency of the entire system.
In classical terms, a magnetowire forms a closed path for the magnetic flux, often in the form of a ring-shaped, rectangular or E-shaped core. In engineering practice, magnetic saturation, hysteresis and energy losses due to eddy currents, are taken into account when designing magnetowires, leading to the use of layered cores or those made of powder materials with controlled magnetic structure.
From the point of view of magnetic field analysis, the magneto-core delineates a region of much greater induction than the surrounding air, which allows for simplified modelling of magnetic circuits using methods analogous to the analysis of electrical circuits. In advanced applications, e.g. in magnetic sensors and microwave circuits, special magnetowire structures capable of guiding electromagnetic waves while maintaining certain propagation properties are being designed.
