Theory Of Magnetism And Electromagnetic Induction
Ferromagnetic material has a special property – it can be magnetizing to create temporary magnetic domains.
Every magnetic domain contains two atoms. When an electron moves from an atom to the next atom and stays there temporarily, the two atoms become a temporary magnetic domain.

  • Jun Jonathan Show me an electric transformer that runs on electrostatic induction.

    • Joe Chang Hold 2 billion electrons in each hand, feel the repulsion force between two hands? No matter how long are your arms, the force F=Ke x 4B^2/R^2 is always there. Now wave one hand, feel the other hand waving at same rate?
    • Joe Chang Simultaneously, instantly over any distance.
    • Jun Jonathan That is not a transformer. A transformer is a device that converts alternating current from one voltage to another (e.g. 100v, 110v, 220v). You can buy a cheap one at US$4. So find me a transformer that runs on electrostatic induction.
    • Joe Chang Same principle, same mechanism. The repulsion force between free electrons on the two coils conducts EMF.
    • Jun Jonathan Different principles. Changing current is not necessary for electrostatic induction. It is for electromagnetic induction.
    • Joe Chang All EM phenomena are in fact E phenomena. I can prove it. Light strength decays at 1/r^2. Magnetic force/field strength decays at 1/r^3. Therefore light is not EM but E.
    • Jun Jonathan What has light got to do with transformers?
    • Joe Chang I am saying all EM theories are misinterpretation of E force at work, current in transformers has nothing to do magnetic induction. Magnetic force/field is just circular electric force/field. This is fact, and wake up call for all scientists worship EM theory.
    • Jun Jonathan Current in transformers has everything to do do with magnetic induction.
    • Jun Jonathan Changing current is everything for a transformer. A transformer cannot work on DC but works on AC. Magnetic induction explains it. Your theory makes no distinction between AC and DC. It just concerns itself with presence of electrons.
    • Joe Chang Hold magnets in both hands to replace electrons so you can feel the repulsion force between your hands. Now if you wave one hand in and out, it is radiation, up and down, it is induction. Both are energy over distance. The later is the mechanism of the transformer. The radiation is the mechanism of light. Thank you for the question.
    • Jun Jonathan Moving your hands holding the magnets up and down does not make a distinction between AC and DC.
    • Joe Chang It does, try it, the other hand must/will move in the opposite direction due to the repulsion force. If attraction force, both hands will move in the same direction, due to the attraction force. Force and motion rule the universe. As always, good question.
    • Joe Chang My magnets decayed 1/2 cus I tried too much.

    • Joe Chang up and down, you know.

    • Jun Jonathan It does not make a distinction between AC and DC. Find out why a transformer works with AC but not on DC. It will clear your mind on the difference between electrostatic induction and electromagnetic induction. Be open minded.
    • Joe Chang Move your hand up and down, the other hand will down and up, move one hand up and up and up, the other hand only move down once. Perfectly explained AC and DC. Be open-minded.
    • Jun Jonathan Ok, makes sense. By the way, I am just discussing electromagnetic induction now. Going back, electrostatic induction does not require current at all, just electrically charged objects. Static electricity also does not make a transformer work.
    • Jun Jonathan You mentioned "Electromagnetic induction is a misinterpretation of electrostatic induction." Kindly explain using your electrostatic induction principle why AC makes a transformer work but DC and static electricity do not.
    • Joe Chang Transformers use iron core to transfer AC. AC in coil 1 magnetizes the core to become electromagnet, The magnet domains in the core changes direction accordingly, induces AC in coil 2 and 3. Good question.

The photoelectric effect is the emission of electrons or other free carriers when light hits a material. Electrons emitted in this manner can be called photoelectrons. This phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry and electrochemistry.
To make sense of the fact that light can eject electrons even if its intensity is low, Einstein proposed that a beam of light is not a wave propagating through space, but rather a collection of discrete wave packets (photons). Wiki
Einstein clearly stated that he knows not what are light quanta.
In reality, light is alternating current coexisting with atoms/medium. If the frequency is high enough, it can vibrate electrons moving in solar cells and produce electric current. This is the true mechanism of so lied photoelectric effect theory.
