Magnetotactic bacteria (or MTB) are a polyphyletic group of bacteria discovered by Richard P. Blakemore in 1975, that orient along the magnetic field lines of Earth's magnetic field.

Magnetotactic bacteria thrive under magnetism and also have the power to sense the magnetic field beneath the earth, just as migratory birds do as they travel with the changing seasons. Science projects conducted to verify the existence and biology of magnetotactic bacteria involve exposure to dangerous bacteria, unpredictable reactions and the need for expensive laboratory equipment and procedures

What is it about the nature of a so called “field” that it should induce such an alignment, especially in a living organism for which the scale of Earth’s geomagnetic “field” would seem immensely far beyond the organism’s ability to either detect and/or be influenced by; likewise with Bees, Birds and other animals that functionally utilize these “fields” for directional orientation and other purposes? Not only that, but the bacterial organism also threads the magnetosomes with a “filamentous structure” constructed of amino acids, which were also found to be “aligned in repeats”. When coupled together it is found that “"mature" magnetosomes are strung like pearls on a chain along a filamentous structure, which is similar to a cytoskeleton.”

Primal living bacteria are constructing the internals necessary for processing the “forces” of electrodynamic “fields” in Nature, they are aligning their physical constitution in accordance with the Earth's magnetic field? Nature sprinkled "living iron filings" on the floor of the seas. In the deeper recesses of the creature it is found that the Magnetite Crystals, which are also found in the human body, facilitate the “opening and closing of trans-membrane ion channels” i.e. Nature’s version of the “gates”, or analogous “spark gap”! :

The orders of magnitude scaling is mind blowing but that is a really small EMF inducing critter.
