Pyromagnetic

Part of speech: adjective

Definitions

1. A unique behavior of certain materials where their magnetic characteristics shift in response to temperature variations
2. The alterations in magnetic properties observed in specific substances when they are heated or cooled
3. A phenomenon where specific materials exhibit changes in their magnetic properties due to temperature fluctuations

Etymology: Magnetic, the root of this word, goes back to ancient Greece. "Mágnēs" was the name for a stone, probably lodestone, and the source of the Greek name is uncertain: it may come from a place called Magnesia in Asia Minor, though that link is itself unproven. The Latin "magnēs" carried the word into Europe, and English took it up as "magnete" in the Middle English period, later shaping it into "magnetic" by adding the "-ic" suffix from Latin "-icus." The prefix "pyro-" comes from Greek "pûr," meaning fire. Its Latin form "pyr" appears in many modern scientific coinages, such as "pyrotechnics," and it reflects the familiar connection between fire and heat that runs through those terms. "Pyromagnetic" is a plain compound: "pyro-" plus "magnetic." It describes how a material's magnetic behaviour responds to heat, so the word joins two classical elements into a technical term for a modern scientific idea.
