How bently nevada proximity sensor works

A mail thread from my mail box, i was answering a question by an engineer about proximity switches. Question was - how bently nevada proximity sensor works

Microwave and RF radiates energy. - You know when a magnet is moved near small nails it make them Move ! If you make an DC electromagnet, it make the nails move again.
But when you keep swapping the polarities, That is with an AC supply it generates a field or radiates an energy. Right from the Toy generator with magnets to the Sun it is the same. The highest form of sun is it radiates photons.
RF is nothing but a Magnet rotated at high speed which is called frequency. This energy can cause food to cook in your microwave oven or a proximity sensor to gauge the gap. It even helps people when the have a sun bath.
I have seen even an old Analog Joystick of a Machine has this induction method to position objects. Study Links below for helping you understand better.
