Constants and convenience functions
SNMRForward exports values of a number of useful physical constants related to the physics of the SNMR technique.
SNMRForward.μ0
— Constantmagnetic vacuum permeability (Newton/(Ampere^2))
SNMRForward.γh
— Constantgyromagnetic ratio of the hydrogen nucleus (bound in water) (radians/(second Tesla))
SNMRForward.ħ
— Constantreduced Planck's constant (Joule second)
SNMRForward.kb
— Constantboltzmann constant (Joule/Kelvin)
SNMRForward.nh2o
— Constantnumber density of water (m^(-3))
SNMRForward.mag_factor
— Functionm0 = mag_factor(temp)
Returns the ratio between the magnetisation of completely saturated water (100% water content) and the ambient magnetic field at thermal equilibrium.
Parameters:
temp
: temperature in Kelvin.
Returns:
m0
: magnetisation ratio, in Amperes per (metre Tesla).
