we can show it by experimenting. for eg. iron (which prevents self demagnetisation) also attracts magnets

How does a magnet attract pins?
Stroke a magnet down the length of the pin repeatedly. The proximity and movement of the magnet along the pin cause some of the iron molecules to become aligned like those in the magnet. The more strokes, the stronger the magnetic field in the pin will become, up to a certain threshold (the number of iron molecules available and able to align in the pin is limited).
How can you show that a given bar is a magnet?
The following two methods are really the same idea:1). Test against a known magnet. Observe whether there is an attraction or repulsion between them.2). Hang the bar by a string from its mid-point. Observe whether it shows a tendency to align itself in a preferred direction.Another method:3). Observe whether the bar picks up paper clips. ---- If you have two bars and are told that one of them is a magnet but the other is not, and you are not allowed to use any other metal, string, etc. to determine which is which, see which one is attracted to the middle of the other bar. That one's the magnet.
How many pieces of celery make 3 ounces?
I can show you one piece, or chop it into 100 pieces and still be at 3 ounces
What is the colour of iron after rusting?
As for the most of rough surfaces of cast iron, the color is grey. Such as normal grey cast iron and ductile iron. The ductile iron will be more white than grey cast iron. There are few types of vermicular cast iron, which are black. The white cast iron will show white color. So, cast iron has different color, such as grey, black, white according to different types. However, most of cast iron castings need surface coating, such as painting or electroplate, so they will show different colors than their own.
Is the magnetic field the area around the magnet where the force acts?
Magnetic domains are microscopic areas of a solid where the atoms all have their magnetic moments aligned. If these domains are randomly aligned then a ferromagnetic material like iron or nickel will not have any permanent magnetism. If these domains start to align with each other the bulk material will show permanent magnetism. The area around a magnet where the force acts is the magnetic field.
What can you use to show the magnetic field of a magnet for people to see?
Little bits of other magnet. Iron filings - the small pieces of metal will floow the magnetic field lines.

How do you know if There is iron in a object?
Iron is magnetic, so using a magnet with show if something is made of iron. Iron also rust like steel(which is part iron) so that can be an easy indicator of if it might be an iron alloy.
How can you determine the poles of an odd magnet?
You place the magnet under a piece of paper, and then sprinkle some iron filings on the paper. The iron filings will line up along the magnetic lines of force, which will show very clearly where the magnetic poles are.
How can you determine the poles of an odd shaped magnet?
You place the magnet under a piece of paper, and then sprinkle some iron filings on the paper. The iron filings will line up along the magnetic lines of force, which will show very clearly where the magnetic poles are.
Are dimes magnetic?
If you mean, are dimes attracted to a magnet, the answers are No for US dimes and Yes for Canadian dimes.American dimes are made of copper and a small amount of nickel. While the metal nickel is in fact attracted to a magnet there's not enough (only about 8.3%) in an American dime to show any attraction.Canadian dimes were made of pure nickel up till the end of the 1990s, and have been made of steel since then. Both of these metals are strongly attracted to a magnet.

it tugs on the iron pieces in the sand causing ripples.

What is Gilbert experiment?
There are several experiments known as Gilbert's Experiment, but the most common is in induced magnetism. This showed that an piece of iron became temporarily magnetic when placed on a magnet. This is why sprinkled iron on a paper over a bar magnet seems (but actually does not) show magnetic lines of force. Instead the iron particles just obey Gilbert's Law of Induced Magnetism.
What happens when you place iron fillings around a magnet?
The fillings align themselves according to the magnetic field created by the magnet. *See the related links to images of the fillings behaving this way, along with a drawing representing the magnetic fields to which the filings align. You can see how the fillings behave similarly in each of the different photos. (see also related question below)
