The newly bought electromagnetic cooker steamer makes a lot of noise when boiling water. What happened?

Because it is electromagnetic vibration sound, it is the performance of the normal operation of the induction cooker, but the noise of different models is different, and the size of this sound is directly proportional to the power. In addition to the sound of electromagnetic reaction, the sound of water droplets bursting will be added.

Boiling water will make a louder and louder sound, because the air in the water is heated at the bottom of the pot, its volume expands, and it gradually rises and leaves the bottom of the pot. Finally, when the water surface bursts, the more bubbles there are, the louder the sound is. After the water is boiled, the dissolved air in the water is almost exhausted, but the water itself forms convection and boils, so the sound is not big.
