5-6 minutes or so

This depends on how much maximum power you use on your induction cooker, how big the pot is, how much water you use, and the standard of cooking.

Boiled eggs should just start to boil the water, can keep the water on the power to keep about 5 6 minutes continuous cooking. Should be able to eat.

Induction stove, also known as induction cooker, the first household induction cooker was born in Germany in 1957. 1972, the United States began production of induction cookers, induction cookers in Europe, the United States and Japan in the early 1980s began to sell.

The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the use of alternating current through the coil to produce a constant change in the direction of the alternating magnetic field, in the alternating magnetic field in the conductor's internal will appear vortex current (the reason for the Faraday's Law of Electromagnetic Induction), this is the vortex electric field to promote the conductor in the current carrier (the pot of electrons and never iron atoms) due to the movement of the vortex electric current of the Joule thermal effect to make the conductor The Joule heat effect of the eddy current causes the conductor to heat up, thus realizing heating

The surface of the induction cooker is a heat-resistant ceramic plate, and the alternating current passes through the coils under the ceramic plate to generate a magnetic field, which produces eddy currents when it passes through the bottom of the iron pots, stainless steel pots, etc. The bottom of the pots heats up quickly to heat up the food. Stove top is a high-strength, impact-resistant ceramic plate (crystallized glass), the bottom of the table is equipped with a high-frequency induction heating coil (i.e., excitation coil), high-frequency power conversion device and the corresponding control system, the top of the table is placed on the bottom of the cooking pot.

The working process is as follows: current and voltage through the rectifier converted to DC, and high-frequency power conversion device to make DC into more than audio high-frequency alternating current, high-frequency alternating current added to the flat hollow spiral induction heating coil, which produces a high-frequency alternating magnetic field, and its magnetic lines of force penetrate the ceramic plate of the cooker and the role of the metal pot. In the cooking pot body due to electromagnetic induction there is a strong eddy current, eddy current to overcome the internal resistance of the pot body flow to complete the conversion of electrical energy to heat, the resulting Joule heat is the heat source of cooking.

The material of the pot must be iron or alloy steel, with its high permeability to strengthen the magnetic induction, which greatly enhances the vortex electric field and vortex heat power. ? Other materials of cookware due to the material resistivity is too large or too small, will cause the induction cooker load abnormally and start automatic protection, can not work properly. At the same time, due to the iron to the magnetic field absorption is sufficient, the shielding effect is also very good, which reduces a lot of magnetic radiation, so iron pot than any other material cookware are also more secure.

In addition, iron is the body's long-term need to ingest the necessary elements, but the human body can only absorb the two-valent iron, iron pan stir-fry contains three-valent iron, however, the body's reducing vitamins can be converted to 3-valent iron to 2-valent iron to facilitate absorption.
