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
