Hematite...I was wondering that too. They are pretty cool.
Iron has magnetic properties and magnets will "stick" to it.
No--those things are made up.
Those things
Magnetic field is made up of magnetic lines.
Graphite is not magnetic as it is made out of carbon. E.g; Pencil lead is mostly made out of graphite, it is NOT magnetic.
Oil is not magnetic, but magnetic substances can be made from it.
no because they are not magnetic and their not made of magnet
no
the magnetic keepers are made up of insulators. generally wood
Everything made of iron is magnetic.
Light, and the entire electro-magnetic spectrum, is made up of photons, which are not elements. Electricity is composed of energized electrons - again, not elements. Lastly, gravity, the strong, and the weak forces are not made of elements (if they are made of things at all).
no,chalk is not magnetic because it is not made out of either iron or steel or otherwise it is not made out of meatal
