Induction cooking is based on electromagnetic induction, a principle discovered by Michael Faraday in the 19th century. The core idea is that a changing magnetic field can induce an electric current in a conductor.
Beneath the glass-ceramic surface of an induction cooktop, there is a coil of copper wire and when electricity flows through this coil, it generates an oscillating magnetic field. If a compatible pan (with ferromagnetic base) is placed on the cooktop, the magnetic field penetrates the pan's metal surface.
This causes eddy currents (circular electric currents)to form within the pan's base. These eddy currents encounter electrical resistance in the metal of the pan, producing heat energy directly within the pan itself.
This is different from gas or traditional electric stoves, where heat is first generated in the burner and then transferred to the pan. The heat generated within the base of the induction pan is then conducted upwards into the food. This process if highly efficient, as heat is generated only where it is needed.
Not all cookware is compatible with induction hobs. To work on an induction cooktop, a pan must have a base made of ferrous (magnetic) metal, such as cast iron or stainless steel. Here's what to look for when choosing induction-friendly cookware:
Common materials include cast iron, carbon steel, and magnetic-grade stainless steel. (Aluminium, copper, and non-magnetic stainless steel do not work unless they have an induction-compatible base).
High-quality induction pans are often have a multi-layer construction which consists of a stainless-steel exterior (for strength and corrosion resistance) and aluminium or copper core (for better heat distribution).
Induction pans must have a flat and smooth bottom to maximise surface contact with the induction cooktop. Warped or uneven bottoms reduce efficiency by affecting the magnetic field interaction.
Some induction pans have a non-stick ceramic or PTFE (Teflon) coating which does not interfere with induction but affects usability and cleaning.
Faster Heating Times - Induction pans heat up almost instantly, reducing cooking time significantly. The direct transfer of energy ensures that food reached the desired temperature more quickly than with traditional methods.
Energy Efficiency - Because induction cooktops heat only the pan and not the surrounding surface, they are more energy efficient. Less heat is wasted, making induction an environmentally friendly and cost-effective choice.
Temperature Control - Chefs require precise temperature control for delicate cooking techniques. Induction pans allow for quick adjustments, preventing overheating and ensuring consistent results.
Even Heat Distribution - Induction-compatible pans, particularly those with multi-layered bases, provide uniform heat distribution, reducing hot spots and enhancing cooking performance.
Safer Cooking Environment - Induction pans are often made from high-quality stainless steel or non-stick materials, making them easy to clean. Additionally, since induction hobs do not product direct heat, spills and splatters do not burn onto the surface, making clean-up effortless.
Induction pans are an investment for chefs seeking efficiency, precision, and safety in their cooking. With rapid heat response, energy efficiency, and superior control, they enhance the cooking experience in both professional and home kitchens. p> At Russums, we offer a wide range of high-quality induction-compatible cookware designed for professional chefs.
