The kanji 磁 primarily conveys the meaning of "magnetism," "magnetic," or "magnetic force." It refers to the physical phenomenon associated with magnets, their ability to attract or repel materials, and the properties related to this force.

The kanji 磁 is a phono-semantic compound (形声文字). The left side is the radical 石 (いし), meaning "stone" or "rock," which provides the semantic component, indicating that the original magnets were discovered in rocks. The right side 司 (つかさ) provides the phonetic component, indicating the sound. The combination of 石 and 司, therefore, creates a character that suggests a "stone" with the "sound" of 司 and pertaining to the properties of magnetism.
