IPA: /ˈmæɡ.nɪ.taɪ.zə.bəl/
KK: /ˈmæɡnɪtaɪzəbl/
Able to be made into a magnet or to attract iron and other materials.
Some materials are magnetizable, meaning they can become magnets when exposed to a magnetic field.
Magnetizable → It is formed from "magnet" (from Latin *magnes*, meaning lodestone or magnet) and "-izable" (meaning capable of being). The word "magnetizable" means capable of being magnetized or turned into a magnet.
Think of a 'magnet' that can be 'turned into' something magnetic — that's what 'magnetizable' means.
