There is a bar in my hand. When I suspend it using a thread, it aligns itself such that one end faces the geographic north direction. It also attracts items made of similar materials. What can this bar be considered analogically similar to?
A bar magnet
A bar magnet aligns itself such that the north pole of the magnet always faces the geographic north. And a magnet attracts iron and other magnetic substances. Hence the bar can be considered analogically similar to a bar magnet.
