Firstly, it is known that deposited scale often adheres to a large amount of heavy metal ions, which are easily dissolved in water during repeated heating, and fragments or particles of the scale enter the stomach of a human body and react with hydrochloric acid to release calcium magnesium ions and carbon dioxide, the former being necessary substances for forming stones, the latter being flatulence and uncomfortable, and the gastric ulcer patients may also have a risk of gastric perforation. Secondly, in the self-heating area of the magnetic conduction container, the burning and wall sticking of liquid or objects occur, which is also a problem difficult to solve by an electromagnetic heating mode, the problem greatly affects the quality of electromagnetic heating, and the material deterioration of the self-heating area of the magnetic conduction container is advanced, so that the service life of the magnetic conduction container is damaged, and other harmful substances, such as benzopyrene, are released to influence the body health of people.

Therefore, the two problems of the electromagnetic heating and the electric heating mode with extremely high heat conversion rate still apply to people's daily life and production activities well by how to scientifically, reasonably and safely utilize the electric heating mode.
