Our B-H hysteresis loop generator is an efficient design-assisted tool developed to simplify magnetic material analysis. By entering your specific parameters, the tool instantly generates a precise chart depicting the material's hysteresis loop and magnetization behavior. It eliminates the need for manual plotting, allowing you to visualize key magnetic characteristics with professional accuracy.
Input the parameters:
SI unit
Symbol
1) Initial permeability:
---
μᵢ
2) Rayleigh constant:
m/A
λ
3) Néel coefficient:

α
4) Saturation magnetization:

Note: 2) Rayleigh constant: The Rayleigh constant describes the initial resistance to magnetization in low magnetic fields, reflecting the irreversible 'jumping' of domain walls as they overcome microscopic obstacles like impurities or stress. This phenomenon is a direct manifestation of the Barkhausen effect and accounts for early-stage energy loss in the material.
3) Néel coefficient: The Néel coefficient relates to stress fields and structural defects, such as dislocations or non-magnetic inclusions, which create local demagnetizing fields. These microscopic imperfections hinder magnetic moments from aligning with high external fields, serving as the primary cause of magnetic hysteresis and coercivity (Hc).
