Can the effect of a magnetic field can be observed using none metal filings?

Yes, the effect of a magnetic field can be observed using non-metal filings, such as certain types of plastic or composite materials that can be magnetized. When placed in a magnetic field, these materials can align themselves with the field lines, demonstrating the influence of the magnetic field. However, the visual effect may be less pronounced compared to using ferromagnetic materials like iron filings, which more vividly show the field's structure.
