a mixture of iron filings and sand
if we have a mixture of sand salt and iron first the iron well be separated with the magnet then the remaining mixture will be put in water where the sand will goes to the bottom. at last the water will be evaporated and the salt remains
Magnets attract Ferromagnetic substances strongly. They contain atoms which don't have any specific direction. When they come under magnetic field, they get direction towards it and get attracted.
It depends, if the metals are all magnetic (neodymium, iron, etc.) all of them will be pulled together to the magnet. But if the metals are different, (aluminum & iron) then the magnetic substance will be separated.
Magnets can separate aluminum, nickel, and i think steel, but I'm not sure
It depends on what material it is. If it's a metal that's attracted to a magnet, yes. If it's a material such as plastic, no.
Mainly ferro magnetic substances such as iron are attracted heavily.
Magnets can separate metal from garbage and iron ore from sand.

conclusion
A magnet is used to separate iron from non-ferrous material in the pulverized ore.
ferromagnetic
The material should have high retentivity so that the magnet is strong and high coercivity so that the magnetisation is not erased by stray magnetic fields
The strength of a bar magnet comes from the way the electrons in the outer shell align. The length is less important that the material. Most bar magnets are made from iron, a fairly inexpensive material. Other materials can produce far more powerful magnets but are far more expensive. As a result, they are only used for special purposes.
Yes, we can see the use of iron oxide (the Fe2O3 kind, which is iron (III) oxide) used in magnets. There are a number of different things that could be used in a magnet, but simply using this material, often referred to as ferrite, and a little bit of some other materials to make up the ferrite, will allow for the construction of a magnet.
A magnet. The magnet will attract the magnetic material to it and so separate the magnetic material from the mixture.

Salt will not be attracted to a magnet. A magnet can be used to separate the two. Heterogeneous means it can be mixed but it is not chemically combined
One commonly used method to separate aluminium pieces from salt is by using a magnet. Since aluminium is not magnetic, the magnet can attract and separate the aluminium pieces from the salt. Another method is to dissolve the salt in water and then use filtration to separate the larger aluminium pieces from the saltwater solution.

They basically work just like any other permanent magnet. The magnet, and the magnetic material (iron-based) in the refrigerator, attract one another.
Try a magnet. A magnet picks up iron. It does not pick up aluminum.
because magnet has a property that can attract metals/metal particles
Run a magnet over the mixture. The iron particles will be attracted to the magnet and the magnet will leave behind the sand.
