Question 1

Why do induction hobs need special pans?

Accepted Answer

Because an induction hob does not produce heat at all — **the pan is the heating element**, and only certain metals can perform that role.

**How it works.** Beneath the glass surface is a coil of wire carrying a rapidly alternating current, generating a rapidly changing magnetic field. When a **ferromagnetic** pan sits on it, that field induces circulating **eddy currents** in the base of the pan. The pan's electrical resistance turns those currents into heat, directly in the metal. **Magnetic hysteresis** — the energy lost as the material's magnetic domains flip back and forth — contributes further.

The hob surface itself stays relatively cool, warmed only by contact with the hot pan.

**What works:** cast iron, carbon steel, enamelled steel, and **magnetic stainless steel** — specifically ferritic grades. Many quality stainless pans have a **bonded ferromagnetic disc** in the base precisely so they work on induction.

**What does not:** aluminium, copper, glass, ceramic, and **austenitic stainless steel** (the common 18/10 non-magnetic grade). These are either non-magnetic or too conductive to develop useful eddy currents.

**The test is trivial:** stick a fridge magnet to the base. If it holds firmly, the pan will work. If it falls off or clings weakly, it will not.

**Other requirements beyond material:**

**A flat base**, since the coupling depends on proximity — a warped or ridged base performs poorly.

**Adequate diameter.** Hobs have a minimum pan size to detect and couple properly; a small pan on a large zone may not register at all.

**Why induction is efficient.** Energy goes directly into the pan rather than heating a burner, a hob surface and the surrounding air. Efficiency is typically around 85–90% against roughly 40% for gas.

**Interface discs** exist to adapt non-magnetic pans, but they reintroduce the losses induction avoids.

Question 2

Why do my pans warp on the hob?

Accepted Answer

Because metal expands when heated, and if one part of the pan expands faster than another, the resulting internal stress bends it. The technical term is thermal shock when it happens suddenly. The

Question 3

What are the essential safety tips for using an induction cooktop?

Accepted Answer

To ensure safety while using an induction cooktop, use compatible cookware, keep the surface clean, monitor cooking, and take precautions to prevent burns.

Question 4

When should I use a stainless steel pan instead of a non-stick one?

Accepted Answer

Use stainless when you want browning, high heat, or a sauce made in the pan. Use non-stick when you want release and easy cleaning with delicate food. They are complementary tools, and a kitchen with

Question 5

What safety features should I look for in an induction cooktop?

Accepted Answer

When choosing an induction cooktop, look for safety features like auto shut-off, child lock, overheat protection, pan detection, and residual heat indicators to ensure safe cooking.

Question 6

Why does my non-stick pan stop being non-stick?

Accepted Answer

Because the coating is a thin polymer layer bonded to metal, and everyday kitchen use degrades it in several ways at once. A non-stick pan is a consumable, not a permanent item, and understanding

Question 7

How do I care for a cast iron pan?

Accepted Answer

Cast iron is more forgiving than its reputation suggests, and most of the strict rules people repeat are unnecessary. What actually matters is keeping it dry and maintaining the seasoning. Seasoning
