I mean WHY

Answer 1

Magnets are made from different materials. The gray ferrite (ceramic and iron oxide with some other elements mixed in in small proportions) ones hold a magnetic field that is much less dense than more-recent magnet developments. Neodymium magnets (they’re not pure neodymium) for example, are able to take a much stronger magnetic field.
