magnet... that's the answer for mr. doty's worksheet
Magnetic domains.
Yes. When a material is magnetized the magnetic domains are aligned.
Magnetic materials (materials capable of becoming magnets), such as iron, have the capability to form small magnetic regions, called "magnetic domains". In these, the atoms are oriented in a preferential direction, causing the magnetism; when an external magnetic field is applied, the domains themselves rotate, so that more of them point in one direction than in the other. In that case, the material is magnetic.A magnetic field may also be caused by an electrical current. This is used in electromagnets.
Any material that does not have magnetic domains.
Domains are aligned.
In non magnetized material the domains are not ordered -they do not align with one another.
The domains in a magnetic material is aligned unlike the non-magnetic material which is scattered
One characteristic unique to magnets is their ability to attract or repel other magnets due to their magnetic field. This property arises from the alignment of electron spins within the material, creating a north and south pole. Materials lacking magnetism do not exhibit this behavior as their electron spins are randomly oriented.
The specific arrangement of domains in a material cause this behavior towards other specific materials. Domains can be in such arrangement naturally or but force using a coil of current etc. Domains : in simple world,, its a bunch of atoms bound together and performing like a charged unit which is overall neutral but the edges are significantly positive (one side) and negative (other) .
A magnet is a piece of iron or other material that attracts other iron-containing objects. The characteristic that exists in magnets that does not exist in materials that lack magnetism is the alignment of domains.
The magnetic domains of an unmagnetized material will be pointing in random directions, which is why it is appearing to me unmagnetized. In a magnetized material, they move from north to south.
Magnetic domains.
Yes. When a material is magnetized the magnetic domains are aligned.
The primary difference is that in materials that can be used as magnets, the atoms can form what are called magnetic domains. Individual atoms and small groups of them form these domains, and the domains can be caused to "face the same way" when exposed to a magnetic field. When the field that aligned them is removed, some of the domains don't return to their previous orientation. They stay aligned leaving a residual magnetic field. The materials that cannot be used magnets don't have magnetic domains. If you heat magnetic material and expose it to a strong magnetic field while it's hot (like at or above its Curie temperature), and then you apply a strong magnetic field and maintain the field while cooling it down, the field "impressed" on the material will largely stay there and you've made a permanent magnet.
If a magnet doesn't stick to a material, that means that the material is non-magnetic. Every individual atom is a magnet, but in a magnetic material, there are groups of atoms (called "magnetic domains") that have their magnetic directions aligned. An outside magnetic field in such materials will align some of the magnetic domains in the direction of the magnetic field.
Domains in magnetized materials are all aligned in one direction - those in un-magnetized objects are arranged randomly.
The domains line up
