Induction has established itself as one of the most efficient cooking systems for the home.<\/h2>\n
It heats up quickly, allows precise power adjustment, and optimizes energy consumption. However, it’s also common to encounter questions: pots and pans it doesn’t detect, zones that seem to work better than others, or noises that cause some uncertainty. <\/p>\n
In most cases, it’s not a technical fault, but rather how the hob and cookware interact. Understanding this operation is key to cooking safely and harnessing its full potential. <\/p>\n
How Does an Induction Hob Really Work?<\/strong><\/h2>\nUnlike traditional ceramic hobs, induction doesn’t generate heat directly on the surface. Instead, it produces a magnetic field that activates the heating of the ferromagnetic metal in the cookware. <\/p>\n
Therefore, if the material doesn’t respond to that magnetic field, the hob won’t activate. It’s a physical, not an electronic, matter. <\/p>\n
A simple trick to check if a pot or pan is suitable for induction: hold a magnet to its base. If it sticks, it will work on induction. <\/p>\n
“My hob isn’t heating properly”: common causes<\/strong><\/h2>\nWhen it seems that induction isn’t performing as it should, one of these situations usually occurs:<\/p>\n
1. The cookware is not compatible<\/strong><\/h3>\nIf the material is not ferromagnetic, the hob cannot transfer energy.<\/p>\n
2. The base doesn’t sit correctly<\/strong><\/h3>\nDeformed, too thin, or poorly contacting bases lead to uneven heating. This can result in power loss or cold spots. <\/p>\n
3. The size doesn’t match the zone<\/strong><\/h3>\nEach hob zone is optimized for a specific diameter. A small pan on a large zone (or vice versa) reduces efficiency and can cause intermittent cut-outs. <\/p>\n
Vitrified steel on induction: performance and advantages<\/strong><\/h2>\nVitrified steel performs exceptionally well on induction hobs.<\/p>\n
Steel is ferromagnetic, so it interacts directly with the magnetic field. The vitrification\u2014the layer of fused enamel covering it\u2014does not interfere with this process. Its function is to protect the metal, facilitate cleaning, and provide durability. <\/p>\n
In practice, this translates to:<\/p>\n
\n- Rapid heat-up<\/li>\n
- Good thermal stability<\/li>\n
- Homogeneous distribution when the base is well-designed<\/li>\n
- Precise response to power changes<\/li>\n<\/ul>\n
Furthermore, vitrified steel maintains predictable performance in long cooking sessions, stir-fries, or stews, where consistent temperature is important.<\/p>\n
Why does aluminum need a special base?<\/strong><\/h2>\nAluminum is an excellent thermal conductor, but it is not magnetic. By itself, it doesn’t work with an induction source. <\/p>\n
That’s why many aluminum pots and pans incorporate an encapsulated magnetic steel base. This base acts as an intermediary: the hob heats the steel, and the aluminum distributes the heat throughout the body of the cookware. <\/p>\n
If this base is too thin or poorly adhered, problems can arise:<\/p>\n
