While there isn't a single universal ".docx" file, several authoritative papers and educational documents explore magnetism through research and hands-on activities.
Objects like paperclips or nails that become magnetized in the presence of a magnetic field but lose their strength quickly once removed. Every magnet has a North and South pole
Materials that maintain their magnetism without an external power source.
