Induction cooking | Working theory | Health and Sefty | How induction cooktop work |

Induction cooking is the the amazing technology, it helps in providing efficient heating instead of old method like flame or heating element. its work on the theory of electromagnetic induction.

In above picture there are an induction cook top having an multitasking key panel and several keys for different work. it is safer and efficient then any old cooking method. heating can control easily by this. induction cooking works on the principle of electromagnetic induction, hence its produce heat only in pot placed over top.

Working theory of induction cooking : Induction heating

The induction produce a large heat in the cookware and reduce the time of cooking. its only supports the ferromagnetic cookware, or the cookware having a metallic plate at the bottom. the cook top works on the electromagnetic induction principle.

Electromagnetic induction is the process in which the electric current produce in the circuit due to change in magnetic field around the circuit. when a magnet is passing through the circuit the current produced in the circuit for a short time, this process is known as the induction or electromagnetic induction and the current is known as induced current.

The induction cooktop consist a large coil of copper beneath of the plate of cooktop. when the alternating current (ac) of high frequency and high voltage  is passing in this coil then it produce a large  Eddy Current  in the cookware, due to the continuously fluctuating magnetic flux. since the ferromagnetic metals are not a good conductor of electricity, hence when this large eddy current flowing in the cookware of the metal then it produce a large heat due great resistance of the metal. this heating can be used for cooking.

in above picture the cooktop also contains the cooling fan also, which protect the circuit from  overheating.

Advantage and disadvantage of the induction cooking 

Use of induction cooking is common in many houses. it have lot of advantage as well as disadvantage also.

Advantage

• more safe and efficient than old method of cooking
• producing large heat in instant time
• easy to handle and maintain
• easy to control of heating
• having multitasking panel
• heat loss doesn't take place

 Disadvantage

• consuming more electric power
• doesn't support all kind of cookware
• only work for ferromagnetic cookware

Health issues

According to a report, the induction cooktop produce a low frequency radiation. this radiation doesn't effect on human body but its slightly effect the person close enough to cooktop. this radiation become the cause of the fluctuations in pacemaker implanted in the heart patient.
