geoana.em.fdem.vertical_magnetic_flux_horizontal_loop(frequencies, sigma, mu=1.25663706212e-06, radius=1.0, current=1.0, turns=1, secondary=True)#

Vertical magnetic flux density at the center of a horizontal loop for each frequency

Simple function to calculate the vertical magnetic field due to a harmonic horizontal loop. The anlytic form is only available at the center of the loop.

Parameters
frequenciesfloat, or numpy.ndarray

frequencies in Hz

sigmafloat, complex, or numpy.ndarray, optional

electrical conductivity in S/m. Can provide a complex conductivity at each frequency if dispersive (i.e. induced polarization)

mufloat, complex, or numpy.ndarray, optional

magnetic permeability in H/m. Can provide a complex permeability at each frequency if dispersive (i.e. viscous remanent magnetization)

radiusfloat, optional

radius of the loop in meters

current: float, optional

transmitter current in A

turnsint, optional

number of turns for the loop source

secondarybool, optional

if True, the secondary field is returned. If False, the total field is returned. Default is True

Returns
complex, or numpy.ndarray

The vertical magnetic flux density in Teslas. If secondary is True, only the secondary field is returned. If secondary is False, the total field is returned.

Notes

The inputs values will be broadcasted together following normal numpy rules, and will support general shapes. Therefore every input, except for the secondary flag, can be arrays of the same shape.
