    u rayt so moreover by definition the term magnet isnt capable precise to answer this question
    >----> Why non-metallic object cannot be magnetized?
    yes, but i think the question itself is answerable in an atomic terms and not just by the use of the term magnet.
    There are :

    ferromagnetic

    paramagnetic

    ferrimagnetic

    and diamagnetic materials etc.,

    or also electromagnetics., each are work differently.
    oi additional magnet napud..hehehehhe... murag puno na kaayo akong utok dah... hehehehh....
    pero stick to basics lang ko (paramagnet, ferromagnet, og diamagnet), kay mao mana akong gusto ang makabalo lang sa basics sa tanan butang (science, esoteric, religion, paranormal, etc). ^_^


    daghan man pud factor maka affect sa magnetization sa usa ka diamagnetic material. like temperature, atomic and molecular interaction, and ilang phase of matter (gas, liquid, or solid). If they are in a gas or liquid at room temperature or above, then most likey dili kau sila ma appectahan sa external magnetic field tungod sa kinetic energy sa particle. hehe
    speaking anang mga kinetic energy sa particle or ang ilang friction, unsaon or how heat works in atomic level? or how heat transfer works in atomic level? ky kasagaran sa net puro man heat energy, energy ang ilang ginasulti man gud.
    like kung init ang object, unsay panghibao ana sa ilang atoms (either monotomic or ang mga bounded nga na atoms)?
    nya sa bugnaw nga solid object pud, asa ang magslow ana? ang molecules or ang electrons sa atoms?

    pls. enlighten me mga professors .... heheeheh

    I have a similar question that i think is related to this topic..

    Why are non-metallic objects put in the microwave oven and not "explode", but when you put metallic objects in the microwave oven, supposedly, they will explode kuno?
    tungud cguro kay mobanda2x ang microwave sa metal, or ang metal movibrate nya moproduce og sariling wave form...... aw ambot di man gud ko scientist..heheheeeeh sila nalang motubag ana part kay sila ang expert diri...ehehheheheh

    murag ambot pud..ehehheehe kay la man ko kabalo sa answer sa imong first question..perog kung makabalo nata, aw makabalo napud ta kung related ba xa sa akong question... ^_^

    you are going into the realms of Statistical Mechanics which is a sort of a more general formulation of Thermodynamics which also goes into quantum statistical dynamics. hehehe! Heat transfer, terperautre, and all that stuff are governed by thermal and quantum fluctuations.

    From temperature, you can calculate the possible Thermal energy of the material the relation energy = (3/2)kT where k is the Boltzmann constant. If you know more about the system, you can also calculate the quasi-classical velocity of the particles (atoms, and molecules).

    Bottom line, the answer lies in Statistical Mechanics and more generally in Quantum Statistical Mechanics.

    That is how you explain thermodyanamics even more clearly and also gives rise to many interesting features like the 5th state of matter, the Bose-Einstein Condensate.

    murag ambot pud..ehehheehe kay la man ko kabalo sa answer sa imong first question..perog kung makabalo nata, aw makabalo napud ta kung related ba xa sa akong question... ^_^
    yep yep.. H20 interacts greatly with electromagnetic waves in the Microwave region (icluding radio waves). It basically causes H20 molecules to increase in kinetic energy consequently increasing temperature. Nya most of our food always has water so Boom! Microwave oven. hehehe Mao pud ni nga reason nganong Sonar (sound waves) ang gamiton sa dagat kay ma-absorb raman ang radio waves sa dagat kung radar gamiton. hehehe

    i'm also looking for a quantum mechanics answer, kanang related to electrons or those dipole-moments na answer..

    if mobanda2x sa metal, mobanda2x pud unta sa non-metal..

    food is mostly carbon, hydrogen, and oxygen.. non-metallic.. mu-init ra man sya, but metal, i suppose it gets really hot too, coz naka-try man ko ug butang ug ceramic na dili pure, unya init kaayo.. also, how come microwaveable items kay dili man xa mu-init, but the food you put in the container does..

    it has got to do with the atomic properties of these elements.. i'm curious to that explanation. (nangita ra pud ko ug tubag, kay murag wala ko makit-an sa net, or i dont know if that is the answer im looking for)

    Hello!

    If you are looking for a full quantum mechanics answer, simple net search won't do you any good. You will just get simple explanations like H20 absorbs microwaves and most metals reflect them. I did a search on physical review letters archive. I found these interesting papers which you might be interested in. If you can not access the paper, just tell me which one you want. hehe

    wow, thank you for the definitive answers.. and papers to read on.. i will definitely read them.. this is probably what i really want to read about.. not simple explanations like you mentioned..

    i can access all of them just fine.. i'm accessing them thru the university library's subscription.. cool!

    no problemo! hehehe! I also have course notes from a course I took last year called optical materials. The main interest of the book is on Optics applications but the solutions work for the entire electromagnetic spectrum. Just pm me your email, if you want a copy of it. Dako kau ang file size.. hehehe

    hooowhaaat?!!! ...hehheheh wa na jud koy nasabtan bossing...heheehee.
    ang ako lang gusto mahibal-an kay ang unsay panghibato sa atom kung init or bugnaw ang object. unsa mahitabo sa electron kung init or bugnaw ang object....
    unya unsa pud ang cause nganong mobehave sila that way... i mean unsay particle/magnetism/radiation/etc ang nainvolve para mo behave ang atoms/electrons that way.

    @bluedudes, aw..heheheeheh... ambot lang.
    kay maong mo-init kuno ang pagkaon diha sa microwave tungud kuno sa dipoles sa atoms kay moreact sa radiation/microwave, unya kay wave form mana xa so ang direction sa dipoles magcge sunod2x sa wave sa microwave, whick will cause nga magkabulabog ang molecules, which will cause friction.....cguro..eheheheeheh
    unya regarding sa metallic nga moexplode ang microwave oven, ambot lang jud. basig naay kinalaman sa....... aw ambot...hehehehe... maplip naman ni akong utok sa cgeg basa2x kay dal-on man ko sa akong gibasa dd2 sa complicated nga mga terms with calculations...waaaaaah!!!

    Pinakasimple nga answer sa unsa mahitabo sa atoms kung init o bungaw kay kung init, mas dako ug kinetic energy ang atoms so pas2x kau sila maglihok2x.. if bugnaw, then hinay.. hehe if absolut zero kelvin temperature, then wala na gyud sila ka lihok..mao na siya.. hehehehe atoms or molecules lang ta.. if gusto ka ug behaviour sa electrons at an atomic level in a material for example a solid, then lisod na kau.. maghardcore quantum mechanics na ta.. hehehe! One simple example lang.. Electrons in a Metal can be treated an an Electron gas in a medium. So in a way, you can also have a temperature for the electron gas. hehehe!

    bale by default ang atom as a whole (aka. molecules) kay nagalihok masking walay external source of energy?
