"positive pole" is a correct and usable term in written English.
It is used to refer to the positive terminal of an electrical source or circuit. For example, "The switch was connected to the positive pole of the battery."
The negative pole of the dipolar water molecule binds to positively charged groups; the positive pole binds negatively charged ones.
The positive pole was targeting the developing somatosensory cortex.
Moreover, the ageing procedures are much stronger at the positive pole.
Aluminium dissolved in cryolite-alumina melts migrates in the direction of the positive pole by passage of current.
Cations are electrolytes that migrate toward the negative pole of an electric field; anions migrate toward the positive pole.
Essentially an electrical battery is created, with the cytoplasm acting as the positive pole and the mitochondrial matrix as the negative pole.
The way Catania describes it, an eel is like a battery, with a positive pole at its front and a negative one on its tail.
If an electric field is applied to the metal, the negatively charged electrons move toward the positive pole of the field so that a net current flows in the metal.
The enzymes produced fragments of varying lengths that were sorted by placing them on a gel and then subjecting the gel to an electric current (electrophoresis): the shorter the fragment, the more quickly it moved toward the positive pole (anode).
That strategy has the effect of doubling the strength of the electric field between the eel's positive pole (which is located near the head) and its negative pole (which is located near the tail).
Electrolytic corrosion arises from the passage through the piling of electric currents, causing the pile, or part of it, to become the anode, or positive pole, in what amounts to a galvanic cell, or battery.
