Why do people generally think that traditional electric blankets have radiation, while carbon crystal electric blankets have no radiation? What is the difference between the two heating principles? thank you Electric blankets made of commonly used resistive materials generate heat when electrons collide with conductor atoms when passing through the conductor.

The so-called carbon crystal electrothermal is that the alternating electric field causes carbon atoms to oscillate and collide to generate heat.

It is precisely because of the advantages of carbon crystal material that the heat generation is more balanced, the efficiency is higher, and the energy saving is more, so the use experience will be better.

As for radiation, it is really a drop in the bucket.

In principle, the electric heating system of ordinary resistive materials will generate low-frequency electromagnetic waves due to alternating current, but then again, your carbon crystal material also needs alternating electric field, so it is impossible to have no radiation.

Most importantly, due to their low operating frequencies, the electromagnetic effect is basically negligible and the radiation is almost zero. I personally estimate that it is only one of tens of thousands of mobile phones, so there is no harm. . . Landlord, judge for yourself. . . According to the electromagnetic field theory, there is a nonlinear positive correlation between the ability of the circuit to radiate electromagnetic waves and the circuit frequency. The higher the frequency, the easier the circuit radiates electromagnetic waves and the faster the attenuation.

The real advantage of carbon crystal is that the material itself is very environmentally friendly and healthy. If it is an electric heating system made of inferior resistance materials, the materials used may release harmful substances in the state of reheating, so there is no need to worry about carbon crystals, which is followed by a series of advantages such as power saving, comfort and safety.

The last point is about electric and magnetic fields.

Please refer to Maxwell's geomagnetic field theory, which has a detailed explanation. In short, a changing electric field generates a magnetic field, and a changing magnetic field generates an electric field. The magnitude of the two is related to their mutual derivatives. In electromagnetic radiation, the two are inseparable. Electromagnetic radiation includes both electric field radiation and magnetic field radiation

That's basically it.

I hope my answer can help you!
