It suggests magnetic material is present, but it does not establish every aspect of compatibility. Base size, shape and construction still matter.
What the observation means
A small magnetic insert can behave differently from a full compatible base. The hob's cookware guidance or built-in test, where provided, is the stronger reference.
A useful next step
Check the pan manufacturer's induction suitability and the hob's dimensions. Do not heat an empty pan to test it. Report whether a known suitable pan works normally, using ordinary observations rather than repeated high-power experiments.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
