Study Notes
- Polarity is when an entity contains two distinct and opposite poles that can attract or repel each other.
- It is commonly used in electricity, magnetism, chemistry, and electronic signaling to describe the flow of electrons.
- One pole may have more electrons than the other, creating negative and positive polarity.
- Electrons flow from the negative pole to the positive pole, creating an electric current.
- The movement of charge carriers produces a magnetic field and magnetic polarity that has north and south poles.
- Polarity can also refer to digital communications, audio engineering, chemistry, biology, international relations, and opinion mining.
- In chemistry, molecular polarity refers to the movement of electrons in covalent bonds.
- In biology, polarity refers to cell polarity, or the differences in shape, function, and structure of cells.
- In international relations, polarity refers to the distribution of power in an international system.
- Opinion mining uses machine learning to gauge opinions from social media posts.
