Ferromagnetic material is the perfect example of atoms having the ability to reverse polarity. Iron is the most prevalent of ferromagnetic materials. Iron atoms have the ability to collectively align their polarities relative to the neighboring atoms. When these iron atoms encounter an electric field, they reorient themselves to form polarity crystals.
The energetic structure is the source energy, the etheric origin of each element; the actual physical atom is the reflection. When the ovoid energetic structure of Iron encounters an electric current, it elongates and narrows its diameter, much like a figure skater pulling their arms in going into a fast spin. This increased spin accentuates its polarity and vibratory output.
All the neighboring atoms follow suit, and entire domains of Iron atoms become “magnetized”. They are collectively locked into unified polarity, like soldiers all symmetrically aligned. This mass atomic alignment results in a crystal of unified polarity.
Silicon is another element with the capability of reversing its polarity. Silicon atoms don’t collectively “group align” like Iron atoms to form permanent magnets. They maintain more of an independence from each other to exhibit semi-conductive properties.
