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 is the strongest area of magnetism in the field?
according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.
Cast iron is magnetic because it is made up of iron atoms. Iron atoms are magnetic because they have unpaired electrons in their outermost shell.
How does a paper clip stick to both north and south poles of a magnet?
A paper clip is neutral or not magnetized and when you bring it to a north or south
pole, the opposite little magnets in the clip are attracted to it. If it is kept in contact
long enough, the clip will itself become magnitized.
What are two advantages of artificial magnet over a natural magnet?
- Artificial magnets can be easily shaped into different forms and sizes, making them more versatile for various applications compared to natural magnets.
- The magnetic strength of artificial magnets can be controlled and manipulated through processes like magnetization, allowing for a more customizable and precise magnetic field.
Are magnets attracted to steel?
The three elements effected by magnetism are Iron, Nickel, and Cobalt. Steel is a iron alloy.
Generally speaking, yes , steel is magnetic. But it should be noted that there are a number of steels that are not magnetic. In order to answer this question, you must first identify the type of steel. Steel can also be magnetized[or made to be magnetic] using an electric field.
Why is the magnetic length of a bar magnet less than the actual physical length of it?
The magnetic length of a bar magnet is less than its physical length because the magnetic field around the magnet extends outward from the poles, so only a portion of the magnet's length corresponds to the region where the magnetic field is strongest. The magnetic field weakens as you move away from the poles, so the effective length of the magnet for magnetic interactions is shorter than its physical length.
I have some serpentine beads (though they were sold just as "green/black beads" at walmart) and a serpentine tumbled stone... the beads stick to a rare earth magnet but the tumbled one does not. Maybe the serpentine that you have is like the beads from walmart... man-made with materials that are magnetic. I don't think real serpentine sticks.
Why does freely suspended magnet always point in the same direction?
A freely suspended magnet will always point in the same direction because it aligns itself with the Earth's magnetic field. This causes one end of the magnet to point towards the Earth's magnetic north pole and the other end to point towards the South pole.
How are magnetic rocks magnetic?
They have the electromagnetic force in which two objects are attracted to one another in a specific field or range.
It happens usually when the rocks contain iron which is the most important magnetic material.
Why would 1volt 12amps have a stronger magnetic field than 12volts 1amp please explain?
The strength of a magnetic field is determined by the product of current and number of turns of wire in a coil (ampere-turns). In the case of 1V and 12A, the ampere-turns would be 12, while for 12V and 1A, the ampere-turns would be 12 as well. Hence, both configurations would have similar magnetic field strengths.
What type of field lines would two magnets make if two south poles are brought together?
The magnetic field lines from the two magnets would repel each other, causing the field lines to spread out in all directions. This would create a distorted and chaotic pattern of field lines near the magnets.
Can magnets attract through cloth?
Yes, magnets can attract through cloth, but the strength of the attraction may be reduced depending on the thickness and material of the cloth. Thinner and less dense fabrics may allow for a stronger attraction between magnets.
What happens to electrons in an iron object when the object is magnetized?
When an iron object is magnetized, the electrons in the iron align their magnetic moments in the same direction, creating a magnetic field within the object. This alignment of magnetic moments enhances the overall magnetic properties of the iron object, making it magnetic as well.
Do magnets have to touch each other in order to experience a magnetic force?
not always as the south pole of a magnet is magnetic yet it repels another south pole. :D
Is chrome moly steel magnetic?
No. It is electro-chemical. The underlying mechanism of electro-chemical plating is the immersion of a part or component in a solution where the metal to be plated on is ionically dissolved. By applying an electric current across the immersion tank and the item to be plated, metal ions in the solution come out of solution as metal atoms directly on the item. They have picked up the appropriate number of electrons there to become "un-ionized" and will form the metal coating with which we are familiar. A link is provided below.
Why does opposite poles on a magnet attract each other?
This is because there's proton and electron. When a magnet is created, two electrically charged portions are created. In which electron is present in one side and proton is present in the other side. Therefore, when you put two like poles together they repel each other just like trying to when you want to fuse two proton together or fuse two electron together whereas they attract each other when you put the unlike pole together because proton attract electron. Neutron is believed to be with the proton in the magnet. :) Hope this help
Another Answer
The original answer is incorrect as it is describing the attraction and repulsion between ELECTRIC charges, NOT magnetic poles! The simple answer is that there is no easily-explainable reason because, to understand it, we need to know about quantum mechanics.
What are you attracted to if you are chelioproclitic?
If someone is chelioproclitic, they are attracted to attractive lips. This could manifest as a specific attraction to lips or a focus on them during romantic interactions.
What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.
A moving electric charge will produce a magnetic field.
A moving electric charge will produce a magnetic field.
A moving electric charge will produce a magnetic field.
How would you describe magnetic domains?
Each magnetic domain has a magnetic field. When an external magnetic field is applied, the magnetic domains will partially align, so the magnetic fields reinforce one another - instead of canceling one another, which is what happens when they are randomly distributed.
Does copper attract with the south pole of a magnet?
No, copper is not magnetic.
ANS2:Copper is not a magnetic metal so the only ways it would be affected would be through electromagnetism or if the copper were part of a magnetic alloy.What are non magnetic substances?
In non-magnetic materials,the magnetic moments of individual atoms are randomly arranged giving net zero magnetic moment such that these materials are not affected when an external magnetiv field is applied
What do you end up with if yuh cut a magnet in half?
Cutting a magnet in half will result in two smaller magnets, each with its own north and south poles. This happens because the magnetic properties are not lost when the magnet is cut.
Why are magnetic field lines closed and continues curves?
Magnetic field lines are closed and continuous curves because they represent the direction of the force experienced by a magnetic north pole placed in that field. The lines form closed loops because magnetic field lines never start or end; they always form complete loops that return to their origin. This continuous nature of magnetic field lines reflects the continuous nature of magnetic fields in space.
How do you make a temporary magnet without electricity?
You can make a temporary magnet by rubbing a piece of iron or steel with a permanent magnet. This aligns the domains in the material, creating a magnetic field. However, this magnetism will fade over time as the domains become disorganized again.
