free_magnetic_energy_density

synthesizAR.models.free_magnetic_energy_density(strand, stress_level=0.3)

Calculate available free energy of the magnetic field using Eq. 1 of Reep et al. [RBK13],

\[E_B = \frac{(\epsilon B_p)^2}{8\pi},\]

where \(B_p\) is the potential component of the field and \(epsilon\) parameterizes the stress level.

Parameters:

• strand (synthesizAR.Strand)

• stress_level (float)
