It's emery.
Magnetite is the magnetic iron oxide mineral. It is a black or brown mineral with a chemical formula Fe3O4, and it is a common iron ore mineral found in many rocks and soils around the world. It is known for its strong magnetic properties.
Magnetite is one of the few minerals that possesses the mineral property called magnetism.
Carborundum, also known as silicon carbide, is a crystalline solid. It has a crystal structure similar to that of diamond and has high thermal conductivity and hardness.
Illegitimi non carborundum is nonsense. It pretends to mean "Don't let the bastards wear you down." Mixing up fake Latin from English words for comic effect is called "macaronics."
It is a pseudo latin phrase (usually "nil bastardum carborundum" - but probably more correctly "illegitimi nil carborundum"?) meaning - don't let the bastards grind you down...
Illegitimi non carborundum
A magnetic rock is called magnetite. It is a naturally occurring mineral that exhibits strong magnetic properties. Magnetite can be found in various rock formations and is used in various industries for its magnetic properties.
most of the time a rock called magnetite.
The cast of Nil Carborundum - 1962 includes: Graham Crowden John Thaw
a rock called Magnetite. :3
yo mama lol
My son who is in 3rd grade is studying magnetite and he has been told that magnetite can be used as a gunpowder and of course that is magnetic.
