Which metals can be magnetized?
IRON OXIDE
What is the formula for iron (III) oxide?
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
What happens if you bring two iron nails close to each other?
Unless one or both iron nails are magnetized, then nothing will happen. If one nail is magnetized, then the other nail will be attracted to the magnetized nail.
Is iron oxide a base?
Iron oxide is not a base.
When steel wool rusts the iron in the steel wool combines with?
iron oxide. the most common types are iron oxide (FeO), iron (II) oxide (Fe2O3), and iron(III) oxide (Fe3O4).
Which metals can be magnetized?
IRON OXIDE
Why hard disc are magnetize with iron oxide?
Hard-disks are coated with iron oxide because it reacts to a magnetic source ! The information on a hard-disk is read and written by a magnetic 'head' which scans across the surface as the disk rotates.
How can you magnetize iron oxide?
It has been found that iron oxide can be magnetized if it is the right kind of iron oxide. We know that iron (III) oxide (Fe2O3) is magnetic, and it can be combined with just a little bit of other stuff to make ferrite, which is commonly used to make magnets.
Which would likely demagnetized a magnetized iron nail?
Dropping it on a hard surface
What were first magnets?
The first known magnets were naturally-occuring magnetic rocks called lodestones. Lodestone is composed of magnetite, an easily-magnetized solid mixture of Iron (II) oxide and Iron (III) oxide. Lodestone's magnetism is induced by the planetary magnetic field generated by the Earth's core. It was soon discovered that pieces of iron metal could be magnetized by stroking them with a lodestone.
What metal is on the floppy disc?
The disc is a thin plastic base material coated with iron oxide. This oxide is a ferromagnetic material, meaning that if you expose it to a magnetic field it is permanently magnetized by the field.
Can iron be magnetised?
Iron is naturally magnetized.
Will iron stick to the south or north of a magnet?
It will stick to either pole, providede that the iron is not magnetized and that it is not above the Curie temperature (the temperature above which iron can no longer be magnetized, named after Marie and Pierre Curie).
What does lodestone look like?
Lodestone is a naturally magnetized piece of magnetite, which is a naturally occurring iron oxide. Lodestone's can be black or gray with a brownish tint and is brittle and broken.
Strongest element that can be magnetized?
iron
What is capable being magnetized?
iron
If your are given three iron rods how would you know which one is not magnetized?
The not magnetized rod will be attracted by both of the magnetized rods.
