Hiszterézisveszteségbl

Hiszterézisveszteségbl appears to be a nonstandard or typographical variant of the Hungarian term hiszterézisveszteség, which refers to hysteresis loss in magnetic materials. In technical literature, hysteresis loss describes the energy dissipated as heat when a ferromagnetic material is subjected to cyclic magnetization, due to irreversible domain wall motion and magnetization reversal at the microscopic level. The term itself is commonly used in the study of transformer cores, electrical machines and magnetic circuits.

Hysteresis loss arises from the area enclosed by the magnetic B–H loop of a material. Each magnetization cycle requires energy to overcome material defects and pinning sites, and part of that energy is converted into heat. The loss per unit volume per unit time (power loss) depends on the frequency of the magnetization cycle and the peak magnetic flux density. A practical rule of thumb is that the hysteresis component of core loss scales with frequency and a material-specific factor, often described by empirical models such as P_h ≈ η f B_max^n, where n is typically between about 1.6 and 2.0 for many steels.

Material and design strategies aim to minimize hysteresis losses, including using soft magnetic materials with low coercivity, employing grain-oriented or laminated cores, increasing insulation between laminations to reduce eddy currents, and optimizing heat treatment. Applications are dominated by transformer cores, inductors, and electric machines, where improved hysteresis performance enhances efficiency and reduces thermal stress.

If encountered as a term, hiszterézisveszteségbl is most likely a misspelling or variant of hiszterézisveszteség.
