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

How does a magnet attract pins?
A magnet attracts pins because it creates a magnetic field around itself. This field exerts a force on the metal material in the pins, causing them to be attracted to the magnet. The pins are made of materials that can be magnetized, such as iron or steel, which allows them to be influenced by the magnetic field of the magnet.
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.
How can you show that a given bar is a magnet?
You can show that a bar is a magnet by observing its magnetic properties. You can use a compass to see if it aligns with the magnetic field of the bar, use iron filings to visualize the magnetic field lines, or see if the bar attracts or repels other magnetic materials.
What is A pattern around a magnet that sHow is its force?
The pattern around a magnet is called a magnetic field. The force of a magnetic field is strongest near the magnet and decreases with distance from the magnet. The force is also influenced by the orientation of the magnet and the material it is interacting with.
Why compass neddle show north side always?
A compass needle is attracted to the Earth's magnetic field, which aligns it with the magnetic north pole. This causes the needle to always point in a northerly direction.
What can you use to show the magnetic field of a magnet for people to see?
You can use iron filings placed on a piece of paper above the magnet to visualize the magnetic field lines. The iron filings will align along the magnetic field lines, making them visible. Alternatively, a magnetic viewing film can also be used to show the magnetic field of a magnet.
How could a student use a magnet to indicate that combining iron an sulfur to produce the mixture of iron and sulfur is a physical change?
The student could use a magnet to show that the combination of iron and sulfur is a physical change by demonstrating that the magnet can still attract the iron in the mixture. Since the iron has not chemically reacted with the sulfur to form a new substance, it will still exhibit magnetic properties. This indicates that the iron and sulfur mixture can be physically separated, confirming it as a physical change.
How does a magnet attract pins?
A magnet attracts pins because it creates a magnetic field around itself. This field exerts a force on the metal material in the pins, causing them to be attracted to the magnet. The pins are made of materials that can be magnetized, such as iron or steel, which allows them to be influenced by the magnetic field of the magnet.
How can you show a magnetic field around a magnet?
You can show the magnetic field around a magnet by using iron filings. Sprinkle the iron filings on a piece of paper or a glass surface placed over the magnet. The iron filings will align along the magnetic field lines, making the field visible.
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.
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.
How would this history reversals show itself on the ocean floor?
it tugs on the iron pieces in the sand causing ripples.

How can an iron nail be magnetized permanentlyShow with a diagram?
To magnetize an iron nail permanently, you would need to stroke the nail along a magnet multiple times in the same direction. This process aligns the domains in the iron, creating a magnetic field along the nail. A diagram would show the iron nail being stroked along the magnet in one consistent direction to align the domains.
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.
Which is used to show the magnetic lines of force?
A magnetic compass or iron filings can be used to show the magnetic lines of force. When a compass is placed near a magnet, the needle aligns along the magnetic field lines, indicating their direction. Iron filings sprinkled near a magnet will also align along the magnetic field lines, providing a visual representation of the magnetic field.
