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 could you show that a loudspeaker has magnet in it?
To demonstrate that a loudspeaker has a magnet, you can use a small ferromagnetic object, like a paperclip. Bring the paperclip close to the speaker; if it is attracted, this indicates the presence of a magnetic field, confirming that a magnet is inside. Additionally, you can disassemble the speaker (if possible) and visually inspect the components, where the magnet is typically found near the voice coil. Finally, measuring the speaker's impedance with a multimeter can also suggest the presence of a magnet, as it affects the electrical properties of the speaker.
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.
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.
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.
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?
A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.
How does a magnet attract pins?

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 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 of reversals show itself of the ocean floor?

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.
