What is the principle of induction cooker heating?
The induction current is greater and the heat generated by the higher, the time required to cook the food is short. To make the induced current is bigger, then through the metal surface flux variation will be bigger, of course, the magnetic field strength will be stronger. As a result, the original coil through alternating current will need to the more the number of turns of winding together.Because of the use of high intensity magnetic induction, there is no electric current in the furnace surface, and therefore, when cooking food, the furnace surface does not produce high temperature. It is a relatively safe cooking utensil
When a magnetic conductive metal surface is placed in the loop coil at the top, the metal surface will be induced current. Because resistance of the metal surface, so the induction current makes the metal surface heat generated, using the heat to cook food.
The principle of electromagnetic stoveWhen a loop coil to the current time, the effect is equivalent to a bar magnet. So the coil surface magnetic field N S generation, which is the magnetic flux through the power supply. If used for AC coil magnetic pole and magnetic flux through the loop surface will change.
