Magnetism
Magnetism is simply an abstraction that people use for the changes in electromagnetic force created by the motion of electric charges. There are different types of magnetism that include electromagnetism, ferromagnetism, paramagnetism, and diamagnetism. To learn more and share your knowledge of magnetism and its types, ask and answer questions here.

Where are the poles of a disc magnet located?
It depends on the magnet, most of them have poles on the flat faces, but some magnets are magnetised on the outside diameter. this means that if you draw a line across the flat face, the south pole is on one side and the north pole on the other side
What is the final substance when iron is magnetized?
The final substance when iron is magnetized remains as iron. Magnetization does not change the fundamental composition of the iron material, but rather aligns the magnetic domains within the iron to create a magnetic field.
Why magnet can attract the soil?
Magnets attract materials that are influenced by magnetic fields, such as iron, nickel, and cobalt. Soils may contain minerals with magnetic properties like iron oxide, which makes them susceptible to being attracted by a magnet.
What are the property of a magnet?
A magnet possess the four properties:
-attractive property
-directive property
-like poles repel and unlike poles attract
-poles always exists in pairs
attractive property: if you bring a magnet near iron filings, the iron filing will get attracted to the magnet. this is the attractive property.
directive property:if a magnet is freely suspended by a thread, it will align itself in the north-south direction. this is called the directive property.
like poles repel and unlike poles attract: a bar magnet's north pole is brought near the north pole of another magnet, it is observed that the the two magnets get repelled. if the same north pole is brought near the south pole of another magnet, the two magnets get attracted.
poles always exists in pairs: when a magnet is cut into pieces, it will always have two poles, that is , north and south. even the smallest magnets will have this property. it is called the dipole property.
Why do the iron fillings align themselves with the magnetic field?
Iron fillings are made up of small magnetic domains that align themselves with an external magnetic field due to the magnetic forces between the fillings and the field. This alignment results in the fillings forming patterns in the direction of the magnetic field lines, making the field around a magnet visible.
I would expect a voltage in both coils of wire.Note that, if the two coils are connected, the voltages (and corresponding currents) in the coils can interact.
Also, if the two coils are NOT connected, they can STILL interact, since a current will produce its own magnetic field.
What are materials attracted by a magnet called?
It is called the magnetic force. This is a force caused by the attraction or repulsion of the magnetic fields of the materials.
What will happen to a compass needle when an aluminium bar is kept in between them?
The compass needle will be unaffected by the presence of the aluminium bar as it is not magnetic. Aluminium is not a magnetic material, so it will not interfere with the function of the compass needle.
No, aluminum is not magnetic because it is a non-ferrous metal, meaning it does not contain iron and is not attracted to magnets.
How is the direction of a magnetic field determind?
The cheap and easy way that we did in school long ago was to put the magnetic on a table, lay a sheet of paper on top, and sprinkle iron shavings on it. I don't know if that always works, but it did for our experiment.
If you are looking to measure the Gauss of the magnet. I would see how much force is exerted on a steel bar and search the Internet to see if there are some simple formulas.
Depending on what you're looking for, I can provide more help.
If you spilled a box of pins how could you pick them up quickly?
Use a magnet to quickly pick up the pins, as they are usually made of metal and will stick to the magnet. Alternatively, use a lint roller or sticky tape to easily lift the pins off the surface. Lastly, you can use a vacuum cleaner with a hose attachment to efficiently suck up the pins.
Why does your silver chain attract to a magnet?
Your silver chain contains nickel if it attracts to a magnet. That means the silver alloy is not sterling .925. It may be a lower grade silver alloy containing less pure silver. Or, it may be a silver colored base metal alloy that contains no real silver at all. Look for a quality stamp or hallmark for further verification of quality.
What happens if you suspend a bar magnet so it can go freely?
if the magnet has a low enough mass, and the string induces very little forces and friction on the magnet, it will act like a compass, the south end will point to the north pole and vice versus with north
What do flag tent magnet have in common?
They can both be used as promotional items for businesses, events, or organizations. Flag tent magnets are versatile marketing tools that can attract attention and be customized with logos or messages.
Why is the north and south's climate different from each other?
The climate in the north and south differs due to various factors such as the tilt of the Earth's axis, proximity to oceans, and atmospheric circulation patterns. The north tends to experience colder temperatures due to its distance from the equator and the presence of polar regions, while the south generally has milder temperatures due to the moderating influence of the Southern Ocean.
Im black to silver and im attracted to a magnet what am i?
You are iron. Iron is a black to silver metallic element that is attracted to magnets.
Increasing the current passing through a conductor results in a stronger magnetic field, not a weaker one. Therefore, increasing the current from 10 A to 15 A should increase the strength of the magnetic field produced by the conductor.
When was the astatic needle invented?
The astatic needle was invented by John Leslie in 1804. It improved the accuracy and sensitivity of early galvanometers used in scientific experiments.
What is the property of floating when two like poles are place one on top of the other?
Magnetic levitation.
Which types of iron are not magnetic?
Ferritic and austenitic types of stainless steel contain iron but are not magnetic due to their specific atomic structures. Additionally, pure iron or wrought iron is typically not magnetic but can become weakly magnetic when exposed to a magnetic field.
What the capacity of magnetic tape?
The capacity of magnetic tape can vary depending on the type and technology used, but modern tape cartridges can typically store anywhere from 1 TB to 30 TB of data. Advanced formats like LTO-8 or IBM TS1155 offer higher capacities compared to older tape technologies.
What plant is attracted to metal?
Some plants, like sunflowers, have been found to accumulate heavy metals such as lead, arsenic, and uranium in their tissues. This phenomenon is known as phytoremediation, where plants are used to clean up contaminated soil or water by absorbing and concentrating the pollutants.
Not necessarily. Permanent magnets are usually made of metals; on the other hand, ANY substance through which a current flows becomes a magnet, and such a substance need not be a metal. For example, a liquid with ions in it can conduct an electrical current.
