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! =]
What else can I help you with?
Are some nonmetals magnetic?
No, nonmetals are typically not magnetic because they do not have unpaired electrons in their outer shells, which are necessary for exhibiting magnetic properties. Materials must have unpaired electrons to create a magnetic field.
Can you make non magnetic things magnetic?
No, we cannot make non-magnetic materials magnetic. The magnetic properties of a material are determined by its atomic structure, so unless the material contains magnetic elements or has been magnetized before, it will not be magnetic.
Are all magnetic materials good conductor of electricity?
Not all magnetic materials are good conductors of electricity. Some magnetic materials, like iron, nickel, and cobalt, are also good conductors of electricity, while others, like magnetite, are poor conductors. The conductivity of a material depends on factors such as its crystal structure and the mobility of its electrons.
Is ceramic magnetic?
No, ceramic materials are typically not magnetic as they are non-metallic and do not contain magnetic properties. However, there are some ceramic materials that can be engineered to exhibit magnetic properties by incorporating magnetic elements into their composition.
Are all metals magnetic materials?
Most metals are NOT magnetic; Iron, Steel (Contains Iron in it), Nickel and Cobalt are the only magnetic materials. Nearly ALL metals are electrical conductors, however, so don't get it mixed up. Last edited (re-written) by 09pwang.
Does a magnetic field pass through all nonmagnetic materials equally?
No, magnetic fields do not pass through all nonmagnetic materials with equal ease. Some materials, like iron, attract and concentrate magnetic field lines more effectively than others, such as wood or plastic. The ability of a material to allow a magnetic field to pass through it is known as its permeability.
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 some nonmetals magnetic?
No, nonmetals are typically not magnetic because they do not have unpaired electrons in their outer shells, which are necessary for exhibiting magnetic properties. Materials must have unpaired electrons to create a magnetic field.
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.
What materials are magnetic?
Materials that are magnetic include iron, nickel, cobalt, and some alloys. These materials have domains that can easily align in the presence of a magnetic field, creating a magnetic moment. Other materials, such as copper and plastic, are not 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!!! ; )

Can magnetism pass through magnetic materials?
Yes, magnetism can pass through some magnetic materials such as iron or steel, but may be blocked or weakened by others like nickel or cobalt. The ability of magnetism to pass through a material depends on its magnetic permeability.
What are some materials that are not magnetic?
plastic marble and nikel
