Focusing on the cathode side reveals that the negatively charged particles are affected by the electric field force, which is opposite to the hydrodynamic resistance force.

Preliminary data show that charge fields _ the layers of positively and negatively charged particles within clouds _ do not fall into the conventional pattern, Krehbiel said.

Lightning strikes start in thunderheads when the strong thermal updrafts that build the towering clouds cause water droplets and ice crystals to collide, creating positively and negatively charged particles.
14.
In 1897 British physicist J . J . Thomson showed the rays were composed of a previously unknown negatively charged particle, which was later named the " electron ".
15.
Positively charged particles on one surface tend to be attracted to negatively charged particles on the other, with the result that the two surfaces as a whole attract each other.
16.
In 1929, Dirac suggested that the building blocks of atoms-- electrons ( negatively charged particles ) and protons ( positively charged particles )-- have antimatter counterparts : antielectrons and antiprotons.

Nutrition scientists began to refine this hypothesis in the early 20th century, emphasizing the role of negatively charged particles ( anions ) and positively charged particles ( cations ) in food.
18.
When any uniform magnetic field is applied across the cloud chamber, positively and negatively charged particles will curve in opposite directions, according to the Lorentz force law with two particles of opposite charge.
19.
In 1897, Thomson showed that cathode rays were composed of previously unknown negatively charged particles, which he calculated must have bodies much smaller than atoms and a very large value for their charge-to-mass ratio.
20.
In 1897 ( in an experiment that could easily have been included in this list ) the British physicist J . J . Thomson had established that electricity consisted of negatively charged particles _ electrons.
