Glossary 
More:
A magnet is any material that has a magnetic field. It can
attract certain materials such as iron and attract or repel other magnets.
Permanent magnets do not rely upon outside influences to
generate their field. They retain their magnetism for a long time.
Electromagnets rely upon electric current to generate a
magnetic field. When the current increases, so does the field.
