Translation guide
The term 'negative pole' is primarily used in scientific and technical contexts, such as electricity and magnetism. In everyday English, it is rarely used outside these fields. This guide focuses on the technical meaning and related expressions.
The terminal from which electrons flow out in a direct current circuit, typically marked with a minus sign (−).
Standard technical term for the negative electrode or terminal in a battery or electrical device.

Commonly used in everyday contexts, such as when replacing batteries. 'マイナス' means 'minus'.

Used in electrochemistry and physics, but can be ambiguous because it refers to the cathode, which may be negative or positive depending on the device. In a discharging battery, it is the negative pole.
