Basic Theory
Hysteresis Loop Bs: saturate magnetic
flux density
Br: residual magnetic
flux density
Hc: coercive force
Basic Theory
Hysteresis Loop
B=H
B B: flux density (tesla) H: field intensity (A-T/m) H : permeability
Basic Theory
Φ
Hysteresis Loop
X H F(F = H l) F Y B
Φ (Φ = B A)
A: core effective area (m2) Φ: flux (Tm2 or webers) F: magnetic force (ampere-turns) l : path length (m) B
