24-25 Magnetism Review

The image below is an example of a _______________ because ...

• permanent magnet; the magnetic domains all lign up.
• non-magnetic material; the individual atoms do not lign up.
• temporary magnet; the atoms in the domain and the domains are all in align
• temporary magnet; the atoms in the domain are aligned, but the domains are not.
