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.
The ability of some materials to become STRONGLY magnetized is related to the fact that the materials form magnetic domains, in which many atoms are aligned in a particular direction. Note that in this case, each atom is a tiny magnet.
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.
The magnetic domains are aligned
magnetic domain.
temporarily magnetic
magnetic alignment
temporarily magnetic
The domains in a magnetic material is aligned unlike the non-magnetic material which is scattered
The atoms are not aligned in one direction known as vectors. Such alignment is necessary for magnetic properties to occur.
Yes. When a material is magnetized the magnetic domains are aligned.
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.

Normally numbers align to the right. However, if a cell has had another alignment specifically set for it, then the number will follow that alignment.

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.
Magnetic fields are only caused by moving electrons. In the case of a current flow, this is the common experience.For a permanent magnet, this effect is caused by the alignment of a number of spinning electrons into a magnetic domain. All their spins pointing the one direction.The magnetic fields and loops on the Sun are caused by currents flowing in the Sun's body. At many thousands of degrees, it is impossible for a magnetic material to exist. This is known as the Curie Temperature - another discovery by Marie Curie - and is the temperature above which a magnetic may be maintained in a material. In essence, the thermal motions of the molecules are too vigorous to permit the creation of aligned magnetic domains.
