Induced magnetism occurs when a material temporarily becomes a magnet when it is exposed to an external magnetic field. This effect happens because the magnetic field influences the alignment of magnetic domains within the material, causing it to exhibit magnetic properties. Once the external magnetic field is removed, the material typically loses its magnetism and returns to being non-magnetic, highlighting the temporary nature of induced magnetism.

The other options imply characteristics that do not accurately describe induced magnetism. Permanent and unchanging magnetism, characteristics of more robust magnetic materials, does not apply here since induced magnetism is inherently temporary. Induced magnetism can occur in a variety of materials, not just limited to certain metals, and it is generally weaker than permanent magnetism, which is retained in materials even after the external field is removed.
