Almost all magnetism is caused by electrons.
Individual electrons have an intrinsic magnetic moment.
In an atom, the electron's angular motion around the nucleus also causes a magnetic moment.
Since all solid materials are composed of atoms and include electrons, the question becomes: why aren't all materials magnetic?
Many atoms only have paired electrons, with the intrinsic magnetic moment of each electron cancelled out by the intrinsic magnetic moment of its paired electron.
Many atoms only have "filled sub-shells", which have zero net angular motion.
Atoms with either unpaired electrons, or unfilled sub-shells, or both, are inherently magnetic. However, in many materials, the magnetic moments of these atoms point in random directions, so they cancel out and the bulk material is nonmagnetic.
It is to do with the pairing of electrons and their dipoles. Basically metals with uneven electrons or half shells are magnetic. Three main metals that are Iron, Cobolt and Nickel. With Iron being the main one.
Hope this helps! =]

∙ 14y agoTheres a certain mineral inside them(called magnelite) which causes magnetism, this is present in lava. When the magnet comes near a magnetic surface the magnelite in them aligns causing them to 'stick'.

Are some nonmetals magnetic?
all non metals are nonmagnetic not all non metals are non magnetic, there is a certain nonmetal that is magnetic but i am not really sure what is it.
Can you make non magnetic things magnetic?
Sort of, in a sense. Some magnetic materials are compounds or alloys of materials that are not, themselves, especially magnetic... for example, Alnico makes better permanent magnets than any of its components (two of which, aluminum and copper, are pretty much nonmagnetic).However, if you're asking if you can make, say, woodmagnetic... no.
Why are some materials attracted to magnets and others not?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
Things that are non magnetic and magnetic?
Magnetic materials: -steel -iron -nickel -cobalt Non-magnetic materials: -aluminum -copper -zinc -gold -silver -wood -plastic -glass Note: Not all forms of Iron are magnetic.
Why material has magnetic property?
The ability of some materials to become STRONGLY magnetized is related to the fact that the materials form magnetic domains, in which many atoms are aligned in a particular direction. Note that in this case, each atom is a tiny magnet.
What is an example of a non-magnetic metal?
Some non-magnetic metals: aluminium, copper, lead, tin, titanium, zinc, brass, bronze, gold, and silver

Are springs magnetic?
It depends entirely on the material of which a spring is made. Some stainless steels are nonmagnetic. If springs are made from any of these steels then they will not be magnetic.

Do magnets repel non magnetic materials?
No, a magnet does NOT have the ability to attract materials that are NON-magnetic (unless it has something magnetic on it, or has magnetic material in it). Duhhh!!! I'm in seventh grade and even I know that!!! ; )

What are some magnetic materials?
iron,copper
What are some materials that are not magnetic?
plastic marble and nikel
Do some non-magnetic materials allow magnetic lines of force to pass through them freely?
yes
Difference between magnetic and non-magnetic materials?
Simple answer: Magnetic materials are affeted by magnets while non magnetic materials are not Advanced: Magnetic (or paramagnetic) materials have unpaired electrons, causing atoms to align in a certain pattern when a magnet is introduced
Which is not a magnetic material?
There are lots of materials that are not magnetic. Some are aluminum, leather, plastic, cloth, paper, wood, etc.
