mikic_magnetic_field_profile

synthesizAR.models.mikic_magnetic_field_profile(s: Unit('cm'), length: Unit('Mm'), ell: Unit('Mm') = <Quantity 14. Mm>, B_0: Unit('G') = <Quantity 1. G>, B_1: Unit('G') = <Quantity 10. G>)

Magnetic field strength along a strand as prescribed by Eq. 4 of Mikić et al. [MikicLM+13]

The analytic magnetic field profile along the strand as a function of the field-aligned coordinate \(s\) is given by,

\[B(s) = B_0 + B_1\left(\exp{\left(\frac{-s}{\ell}\right)} + \exp{\left(\frac{-(L-s)}{\ell}\right)}\right)\]

where \(L\) is the strand length and \(\ell\) is the scale height of the field. The default values of all of these parameters are those used in Mikić et al. [MikicLM+13].

Parameters:

• s (Quantity) – Field-aligned coordinate

• length (Quantity) – Strand length

• ell (Quantity, optional) – Scale height of the magnetic field

• B_0 (Quantity, optional)

• B_1 (Quantity, optional)
