The scientific study of clay is complex. I've only skimmed the surface of this topic. Smectite clays act upon & within the body on a nanometric
molecular level. Heres an explanation of how the electrical field is activated on a molecular level:
"By mixing Pure Colloidal Calcium Bentonite clay with water either internally or externally the expanded particles develop into a large surface which
enables them to pick up many times their own weight of various body toxins. This wide surface is made of a great number of tiny platelets, each with a
negative electrical attraction for positively charged toxins. Bentonite clay's negative charge is responsible for its amazing detoxifying properties:
it is a magnet for many toxic elements present in the human body (heavy metals, pesticides, & free radicals), which are positively charged. This
physical pulling power of Pure Colloidal Calcium Bentonite Clay also has an absorbent action... as toxins are drawn into the porous surface of the
clay....When water is added to Bentonite, the molecular structure changes & an electrical charge is produced. The clay swells like a sponge,
attracting toxins into the mixture & once they are drawn, they're bound to the clay because of the electric charge."

When water is added to the clay, it becomes charged with negative ions which attract ions that have a positive ion charge.

"...It has a very high expansion & ion exchange capacity & is very active as a catalyst in organic reactions – the property which is widely used to
control environmental pollution & toxicity. Structurally, montmorillonite is composed of a sheet of octahedrally coordinated gibbsite [Al2(OH)6]
positioned between 2 sheets of tetrahedrally coordinated silicate [SiO4]4-sheets. The interlayer sheet determines physical & chemical properties of
the mineral. The most important property of montmorillonite is its high cation exchange capacity which happens because Al3+ exchanges for Si4+ in the
tetrahedral sheets, & of Mg2+ cations exchange for Al3+ cations in the octahedral sheets, thus creating a charge imbalance. The defects at the edges
of the clay layers add to this imbalance. The balancing cations of Na+, Ca2+ & Mg2+ are situated between the clay layers. The layers move apart on
hydration which leads to the clay swells & the existing interlayer cations become easily exchangeable. Na+, Ca2+ and Mg2+ as compensatory cations for
the charge imbalance. When the clay is dry the balancing interlayer cations of Na+, Ca2+ & Mg2+ reside in the hexagonal cavities of the silica sheets.
However, when it is hydrated, the cations position themselves between the lamellae & become exchangeable by a variety of cations – metallic &
non-metallic, organic & inorganic, such as H3O+, NH4 +, Al3+, Fe3+ & others. "
Another source discusses the structure & chemical composition of bentonite clay:
"The crystal structure, chemical composition, exchangeable ion type, & small crystal size are responsible for several unique properties, including a
large chemically active surface area, a high cation exchange capacity, & interlamellar surfaces having unusual hydration characteristics..."

This source explains that
in the presence of water, the clay is activated:
"...In the presence of water, the montmorillonite crystal swells & water molecules become deposited between individual silicate layers. Under the
influence of a mineral acid, the exchangeable alkaline earth ions of bentonite are substituted by hydrogen ions...depending on the acid concentration,
temperature, pressure, & reaction time, a more or less pronounced leaching process takes place...This results in a change in the crystalline structure
of montmorillonite & in an increase of its specific surface area & porosity..."

A German Scientist described the properties of bentonite:
"...Individual bentonite particles are smaller than many bacteria. If infected mucous membranes are more or less flooded with bentonite, the bacteria
are completely surrounded by bentonite particles & are thus separated from their source of nourishment & become imbedded in the inorganic material.
Growth & the survivability of the bacteria are thus halted almost instantaneously." --Julius Stumpf, Bolus fur medizinische Anwenduno Darmstadt,
1916, p. 19.
Smectite clays have both properties of Adsorption & Absorption.
Adsorption is when charged particles of other substances combine with charged particles on the outer surface of a clay molecule...For this to happen,
it must contact a molecule of another substance with unsatisfied bonds that carry an opposite electrical (ionic) charge. When the 2 molecules meet,
the ions held on the outer surface of a clay molecule are exchanged with ions held on the outside surface of a molecule of the other substance. Clay
molecules carry a negative electrical charge while toxins, bacteria & other impurities carry a positive charge. When the clay is taken into the human
body, the positively charged toxins are attracted to the negatively charged surfaces of the clay molecule. An exchange reaction occurs in which the
clay mineral ions are swapped for the ions of the toxic substance. The clay molecule is now electrically satisfied & holds onto the toxin until our
bodies can eliminate both.
