SUMMARY
The area of the B-H curve, or hysteresis loop, directly represents the energy dissipated per unit volume during the magnetizing cycle. To calculate this, one must consider strictly magnetic energy, using the energy density formula ~|B|². The relationship B = μ₀(H + M) allows for the determination of magnetization M as a function of the magnetic field H. By performing a piece-wise integration over the hysteresis loop, one can accurately derive the energy density associated with the magnetic cycle.
