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.
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.
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.
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.
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
A. Compasses typically use a permanent magnet.
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.
Yes, it is 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.
ferromagnitisation is the property of certain metals to form permannent magnets. these metals are attracted by magnet, this type of magnitisation is the strongest.
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
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.
