The heating differences between induction cooktops and gas stoves
Question:
The heating differences between induction cooktops and gas stoves
Answer:
The working principle of an electromagnetic cooker is based on the phenomenon of electromagnetic induction. When current passes through the coil, a magnetic field is generated, causing the bottom of ferromagnetic cookware to heat up due to the eddy current effect. In contrast, a gas stove heats the bottom of the pot directly by burning natural gas or liquefied petroleum gas through flames. The differences in these two heating methods result in variations in efficiency: The electromagnetic cooker generates heat directly at the bottom of the pot, thus achieving a higher thermal energy utilization rate; while the gas stove has more heat lost to the air, resulting in relatively lower efficiency. Moreover, the electromagnetic cooker requires the use of flat-bottomed cookware with ferromagnetic properties, which is not suitable for non-magnetic materials like clay pots; while the gas stove has no special requirements for the material of the pot, making its application range more extensive.
