iron colbalt and nickel

∙ 13y ago
Iron, nickel, and cobalt are the most commonly used metals for creating permanent magnets. They have strong magnetic properties and can retain their magnetism over a long period of time. Other metals like neodymium and samarium can also be used to create powerful permanent magnets.

What metals do magnets only attract?
Magnets only attract ferromagnetic metals, such as iron, nickel, and cobalt. These metals have magnetic properties that allow them to be attracted to a magnet.
What type of magnet can only attract materials when it is touching another magnet?
A temporary magnet, such as an electromagnet, can only attract materials when in contact with another magnet or when an electric current is flowing through it. It loses its magnetism when the current is turned off or the magnetic field is removed.
How do you know that is not a huge permanent magnet earths core?
Scientists have studied the Earth's core extensively using seismic waves and magnetic field measurements. The data show that the Earth's core is primarily made of molten iron and nickel, rather than a solid permanent magnet. Additionally, the Earth's magnetic field is generated by the movement of molten metals in the outer core, not by a single large permanent magnet in the core.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What is the difference between permanent pole and temporary pole?
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
What does permanent magnet attracts?
Permanent magnets attract certain types of metals such as iron, nickel, and cobalt. This attraction is due to the alignment of magnetic domains within the metal, causing a magnetic force to be generated between the magnet and the metal.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.

Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
What kinds of irons attract to a permanent magnet?
What, precisely, are these "kinds of irons" you speak of? If you meant "what kinds of metals" ... the ferromagnetic ones, of course.
What is ferromagnitism?
ferromagnitisation is the property of certain metals to form permannent magnets. these metals are attracted by magnet, this type of magnitisation is the strongest.
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
How a magnet could be used to separate different types of metals at a recycling centre?
A magnet can be used to separate ferrous metals (containing iron) from non-ferrous metals. When the magnet is passed over a mixture of metals, the ferrous metals will be attracted to the magnet and can be easily separated out. Non-ferrous metals, which are not magnetic, will not be affected by the magnet and remain in the mixture.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
