About nano

[Reference] Nanometer (symbol is nm) is a unit of length, originally called nanometer, which is 10-9 meters (65438+ one billionth of a meter), that is, 10-6 mm (65438+ one millionth of a millimeter). Like centimeters, decimeters and meters, it is a unit of measurement for length. It is four times the size of an atom and less than the length of a single bacterium. [/quote]

About magnetic waves:

The concept of "magnetic wave" cannot be found on Baidu.

That's right! no doubt

This is not a scientific term at all!

At most, there are only "point magnetic waves"

Then, the concepts of nanometer and magnetic wave are combined.

Literally,

It is the "minimum magnetic disturbance"

Do you really believe this stuff can help you lose weight?

This is another dirty trick of the merchants.

Throw you a few seemingly abstruse nouns.

Lure you into paying.

You can only fool good people who don't understand physics.
