    pero ang akong gusto madungug nga answer is kanang explanation nga nag-involve og magnetic domain, atoms, elctrons, etc. without computations...

    kay ani man gud kuno na, maong ma-magnet ang butang like bakal tungud kay kung naay magnetic field nga moduol sa ilaha, ang domain sa atom nga nakapoint randomly kay mo-align (magnetic domain na), so mao xa.... perog kung dili bakal nganong dili man moalign? (thought naay mga experiment nga kaaya nila palutawun tanan butang including frog, water, etc. BUT kailangan og complex technolgy og very powerful magnets, etc.)


    @fritz, gihinay2x nako tog basa nang link sa wiki nga imong gihatag.
    naa ko pangutana about ani:

    kung mao na, pwede diay mamagnetize ang Oxygen og katong mga atoms nga walay pairs nga electrons? ky diba maong naay water tungud sa 2 hydrogen nga nidikit sa 1 Oxygen (H2O). maong nidikit tungud kay ang Oxygen naay duha ka unpaired nga electrons unya ang Hydrogen kay duna ray 1 ka electron.


    tama ba?

    yep. in a way, sakto.. pero these elements like oxygen have really weak magnetic dipole moments. Kung naa Magnetic field, they still do react pero dili sila ka retain sa magnetic ordering. Tawag nila kay Paramagnetism... Metals, on the other hand like iron have very strong atom magnetic dipole moments. => ferromagnetism. They can retain alignment when exposed to a magnetic field. hehe! mao na usually mga two types of magnetism involved. Ferromagnetism ug Paramagnetism.

    Most ferromagnetic elements are metals because they are arranged in a crystal lattice and thus can retain the magnetic ordering after exposure to a magnetic field. Paramagnetic elements on the other hand are usually don't have order in the arrangement, eg. gas, liquid, bulk solid. so don't retain magnetic ordering.
    pero its quite complicated, kay the entire library of elements in the periodic table have very many peculiar properties. Naay poy Diamagnetism which is how hydrogen behaves. they create an opposite field to an applied external magnetic field, so an resulta kay repulsion. hehe
    Anyway, I don't want to get complicated kay ako maglibog pud ko. hehehe Just think of the magnets we are used to as the ferromagnets. hehehe

    1. ah okeh Ferromagnetism ug Paramagnetism diay.

    2. pero tanan atoms naa may magnetic ordering/direction sa domains nga nakapoint randomly by default. so nganong ang magnetic domain sa non-metallic object di man mopoint sa one direction kung naay outside source of magnetic field?, parihas sa metal nga mopoint sa certain diretion.
    masking pila lang gud kaseconds nga mopoint sa one direction kay naa gud magnetic field nga present.


    btw, ok pud imo explanation kay simple lang sabutable jud kaayo ^_^

    yep, tanan atoms naay magnetic properties.. try type any element sa wikepedia nya tanawa sa properties ang 'Magnetic ordering.' naa gyud na for every element. hehe

    depende pud sa strength sa ilang magnetic dipole moments.. daghan pud other factors nga maka-affect sa magnetic interaction. pero kung naa magnetic fields, mureact gihapon ang atoms with respect to the field pero dili lang sila ka retain kung wala nay magnetic field. hehehe

    mao lage pero ang direction sa magnetic domains di molihok maong dili mamagnetize.


    try nako search tong sound levitation nga gigamit kuno sa Tibetan monks para molutaw ang dakong bato. ky murag makasilip ko dihag hints nga di na magrequire og mga calculations and other complicated scientific terms ^_^. .....



    salamat sa tubag.

    Not all metallic objects can be attract by a Magnet

    Different materials have different characteristics.

    A piece of iron can be pick-up by a magnet but not in piece of a copper wire.

    yep yep, copper is diamagnetic. hehehe

    okeh gets na nako ang tawag aning mga butanga ni..heheheeh mao diay na ilang tawag.

    paramagnets - object nga mamagnetize, but cannot remain magnetize in the absence of external magnetic field
    ferromagnets - mao ning tawag sa mga magnet nato ron. (remains magnetize even in the absence of external field)
    diamagnets - mao ning mga object nga dili mamagnetize tungud sa iyang properties nga mo-oppose ang dipoles sa external field.

    perfect nako ani sa exam!!

    ngotana lang ko ninyo bai,
    diba ang dipoles sa diamagnet kay mo oppose man sa applied external magnetic field, so kung example naay diamagnetic nga object unya atong duulan og ferromagnet sa taas niya. diba dili man mamagnetize kay ang object (katong giduulan og ferromagnet sa taas) ang iyang dipole mo-oppose man sa field sa ferromagnet nga naa sa taas maong mocancel ang ilang attraction (maong dili mamagnet), so kung butangan pajud og ferromagnet sa ubos sa diamagnet (bale naa nay duha ka ferromagnets, ang isa naa sa taas unya ang isa naa sa ubos) unsa ang direction karon sa dipole sa diamagnet? kay mo-oppose man nang diamagnet BUT naka-oppose naman xa daan sa isa ka ferromagnet nga naa sa taas..

    ??

    btw, pwede pud electromanetism ang gamiton instead sa ferromagnet noh? para machange2x ang value sa strength sa magnetic field pinaagi lang sa pagpakusog sa bultahi sa electric current.

    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

    as you said, pwde ra pud electrodynamics or electromagnetism.. moving charges create a Magnetic field, consequently, electric currents create magnetic fields. hehe

    ^ ^ ^

    u rayt so moreover by definition the term magnet isnt capable precise to answer this question
    >----> Why non-metallic object cannot be magnetized?

    There are :

    ferromagnetic

    paramagnetic

    ferrimagnetic

    and diamagnetic materials etc.,

    or also electromagnetics., each are work differently.


    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 soli
    ^ ^

    ys as i say different materials have different characteristics.

    @hizuka

    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?

    I only see it on TV, I want to try, but sayangan ko sa microwave oven..

    so is the explanation for that close to the answer to this question of yours? I'm really curious also..

    along with this topic, how does heat "coerce" covalent bonding (either break or form them)..
