volume conductor मीनिंग इन हिंदी

MEG detects intracellular currents associated primarily with these synaptic potentials because the field components generated by volume currents tend to cancel out in a spherical volume conductor The decay of magnetic fields as a function of distance is more pronounced than for electric fields.
where x of the local x, y, z coordinate system is normal to the volume conductor surface, \ hat { x } and \ hat { y } are unit vectors, and Bz is the normal component of magnetic field.
:: : I just took a brief glance and quickly spotted MoS errors, Wikilinking needs attention ( I noticed potassium, for example ), and there are still citation issues, example : Mauro A ( 1960 ) . " Properties of thin generators pertaining to electrophysiological potentials in volume conductors ".
In Magnetoencephalography it says : " Whereas scalp EEG is sensitive to both tangential and radial components of a current source in a spherical volume conductor, MEG detects only its tangential components . " Could anyone explain to me what is meant by " the tangential and radial components of a current source ".
