MAGNETIC FIELD AND MAGNETIC DOMAINS
The image on the left is a bar magnet. The image on the right is the inside of a paper clip. The arrows in each show domains.
A magnetic field is created because the domains face the same way.
There is no magnetic field in a paper clip because the domains are not lined up. The paper clip is neutral, it is not magnetic.
