Are domains alligned in magnets?
Yes. When a material is magnetized the magnetic domains are aligned.
Is the magnetic field the area around the magnet where the force acts?
Magnetic domains are microscopic areas of a solid where the atoms all have their magnetic moments aligned. If these domains are randomly aligned then a ferromagnetic material like iron or nickel will not have any permanent magnetism. If these domains start to align with each other the bulk material will show permanent magnetism. The area around a magnet where the force acts is the magnetic field.
Why are some iron objects magnetic and others not magnrtic?
If the iron atoms are aligned then the object is magnetic, if they are randomly oriented then it is not. How the object was manufactured may be the cause of the difference, but it always possible to intentionally either magnetize OR demagnetize an object.
What happens to the strength of an electromagnet and field when a stronger ferromagnetic material is used for the core?
The magnetic field would become a magnetizing field as far as the magnetic material is concerned. If the material is dia magnetic then the electrons magnetic moment would get aligned in such a way as the resultant magnetic field within the material becomes perpendicular to the magnetizing one. In case of para, resultant would become parallel to the external In case of ferro, domains get aligned and so intense magnetic induction results.
How do earths magnetic field magnetize an iron bar over many years?
Ferromagnetic materials are randomly distributed, but in a magnetic field, they can become aligned in the direction of the magnetic field. The earth's magnetic field has a fairly stable direction over very long time periods (many thousands of years). :D hope u injoy
A permanent magnet has magnetic properties because?
The magnetic domains are aligned
When the magnetic domains in a material can be aligned but eventually drift out of alignment the material is .?
temporarily magnetic
Why does a magnet lose strength each time you drop it?
The magnetic poles of the magnetic domains are physically jarred and realign. They realign randomly. When a material appears to be strongly magnetized it is because these domains are aligned.
When none of the magnetic domains in a material will stay aligned the material is called?
temporarily magnetic
How are magnetic domains arranged differently in a magnetized material and in a material that is not magnetized?
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.
Groups of atoms with aligned magnetic poles are called magnetic what?
Within a magnet, the separate poles are composed of domains, regions where the individual atoms are aligned with parallel magnetic moments.
How are magnetic domains arranged differently in a magnetized material and in a materials that is not magnetized?
The domains in a magnetic material is aligned unlike the non-magnetic material which is scattered
Why the gold does not show magnetic properties?
The atoms are not aligned in one direction known as vectors. Such alignment is necessary for magnetic properties to occur.
Are domains alligned in magnets?
Yes. When a material is magnetized the magnetic domains are aligned.

Why some iron object magnetic and other not magnetic?

What causes certain materials to be magnetic?
A material is said to be magnetic if a large percentage of the atoms of which it is comprised are capable of being aligned together such that the individual magnetic fields of individual atoms can reinforce each other. Nickel, Iron, Cobalt, Gadolinium and most of their alloys are highly magnetic. ______________________________________________________________________ There Physical Properties and if it is electrically charged in some cases.
