If you hold a permanent magnet the wrong way in an extremely strong magnetic f eld, its magnetization will be permanently reversed. what happens to the magnetic domains inside the permanent magnet during this process?

The domain that is aligned with the applied field will grow, while the domain that is oppositely aligned to the magnetic field will shrink, this is because permanent magnets produces their own magnetic field.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
