An induction symbol is a useful compatibility clue, but the strongest answer comes from the exact pan instructions and your hob manual together. Look for an induction designation on the base, packaging or maker’s product page, then check the base dimensions against the cooking zone you intend to use.

Read the marking in context
A coil-like marking commonly appears alongside other hob symbols. Inspect the whole group instead of guessing from one worn shape. A separate oven or dishwasher symbol answers a different question and does not establish induction suitability.
Circulon directs owners to its induction icon or use-and-care instructions and describes a magnet check as another way to assess suitability. It also explains that the magnetic area of a base can differ from its apparent size. That distinction matters when a pan is labelled compatible yet behaves differently on two zones. Circulon induction guidance
If the symbols are unclear, photograph them while the pan is cold and dry. Include the brand, any article number and the whole underside. An identifiable model gives the manufacturer something concrete to check; a cropped coil symbol may not identify the construction or generation.
What a magnet check can establish
A magnet attracted to the underside indicates magnetic material at that location. It does not measure the entire effective base, certify the pan’s condition or replace the appliance maker’s minimum-size requirements. Check gently on a cold item, keeping the magnet away from a surface it could scratch.
Do not infer compatibility from the colour of the metal. A pan can have a different material in its base from its sides. Equally, a stainless steel description may concern the cooking surface rather than tell you everything about the underside.
| Evidence found | Useful conclusion | Still to check |
|---|---|---|
| Exact maker page says induction | Model is intended for induction use | Zone size and condition |
| Magnet attracts to the base | Magnetic material is present there | Effective diameter and model instructions |
| Generic retailer says all hobs | A claim needs confirmation | Exact product code and manufacturer statement |
| No visible symbol | Marking is absent or unreadable | Manual, packaging or maker support |
Identify every pan in a mixed collection
A set may have grown through replacement pieces, gifts and second-hand purchases. Do not assume that a small saucepan has the same construction as a frying pan carrying the same brand name. Record each model or photograph separately.
This is particularly useful before changing from gas to induction. Make three groups on paper: confirmed compatible, needs identification, and expressly incompatible. You may discover that only one frequently used size needs replacing, rather than buying a complete new set on the strength of uncertain markings.
Record the pan’s job as well. If an incompatible vessel is used twice a year, borrowing or changing that dish’s cooking method may be more sensible than immediately replacing it. A missing everyday saucepan deserves more attention.
When a compatible pan is not detected
Look up the hob’s cookware-detection instructions and permitted pan sizes. Note which zone was selected and the displayed message. Detection problems are not proof that the symbol is fraudulent or that the hob has failed.
Use the appliance’s documented checking routine, if provided. Do not heat an empty pan repeatedly at high power to see whether it eventually works. Avoid adding an adaptor plate unless the appliance and cookware instructions expressly permit that arrangement.
If you contact support, send the hob model, pan model, base photograph and the exact message. Describe whether another known-compatible pan works using the normal instructed method. This gives support a clearer starting point than saying only that the hob rejects steel.
Keep the evidence with the pan
Save the manufacturer page or manual reference with your household appliance records. Write down the date and exact product number, especially if a replacement has a similar name. When you next buy a pan, ask for both an explicit induction statement and the relevant base dimensions. The symbol starts the check; the complete match finishes it.
