Atoms peer-pressuring their neighbors into pointing the same way, permanently.
means The property of materials like iron, nickel, and cobalt that lets them form strong, lasting magnets because their atomic magnetic fields lock into alignment.
from Built from 'ferro-,' Latin for iron (ferrum), fused onto 'magnetism,' itself tracing back to Magnesia, the region in ancient Greece whose ore-rich stones first revealed the pull of lodestones. Scientists coined 'ferromagnetism' to single out iron's especially stubborn, self-reinforcing magnetic behavior from the weaker magnetic effects seen in other materials.
