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.
Where do magnets get their energy to do work like attraction and repulsion?
Permanent magnets have a magnetic field around them. This field is an "area" of force, and the force is derived directly from the uniform motion of a large number of electrons in the ferromagnetic material. Moving electrons generate a tiny magnetic field around their path of travel, and this is the basis of the magnetic force. The "blocks" of atoms that have uniformly moving electrons are called magnetic domains. The aligned domains allow an "over all" magnetic field to be detected and even used by an investigator. The field will interact with ferromagnetic material to attract it, or will, when moved "past" any conductor, induce a voltage in that conductor. A pair of magnets will attract or repel, depending on how they are held or placed. The magnetic field of each one will interact with the field of the other, and the lines of force will push or pull, as suggested.
A cluster of billions of atoms that all have magnetic fields lined up in the same way is known as a?
it is known as a magnetic domian.
What are types of magnetism?
ferromagnetism - permanent magnets, with N and S pole, all the atoms are aligned and 'spin' the same way so the magnetic field is strong in one direction paramagnetism - an object becomes temporarily magnetic when a field is applied and the resulting field is parallel to the applied field diamagetism - a temporary magnetism opposite to that of the applied field
Were is the charged particle flow in a permanent magnet?
I believe it is in the material. It says that everything has charged particles in it. It also says that in order for a material to be magnetic, then, its atoms have to line up in a certain way so that the electrons in the material all have the same general motion. So if it's a permanent magnet, then the charged particles would be in the material.
What is clustered region of aligned magnetic atoms called?
Technically impossible . In a rock , ferromagnetism can create poles , but not in atoms . Atoms cannot be magnetic . Molecules can be polar , which leads to Van der Waals links , but a region's molecule cannot become all lined in the same directions . http://www.youtube.com/watch?v=4VmMr9TWzY4 http://media-2.web.britannica.com/eb-media/65/265-004-9B256ADC.gif Pretty simple , as a matter of fact .
What do permanent magnets contain?
Permanent magnets contain magnetic atoms (almost always iron) whose magnetic poles are all (or mostly) aligned in the same direction.
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 most materials not magnetic?
Magnetism is created by the synchronized spins of atoms with unbalanced electron clouds. The lowest energy states for these unbalanced atoms is to align themselves with nearby atoms and spin in unison, creating the magnetic field we are familiar with. Most atoms have balanced electrons, or have electron configurations which do not have low energy states when aligned, thus no inclination to spin together in large groups, and no magnetic field.
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.
Why metals behave like magnet during electromagnetic induction?
The clusters of magnetic atoms in them, usually scrambled up, all get aligned with the electromagnetic field, so they also exert a magnetic force.
How are the atoms in a magnet arranged?
The atoms in a magnet are arranged in some kind of lattice, but the arrangement of the atoms is not what is important. What is important is that the magnetic dipoles of a good portion of the atoms are all "pointing" in the same direction. The aligned atomic magnetic dipoles form groups called magnetic domains, and these are locked in place making the magnet a permanent magnet. It "permanently" holds its magnet field, and is said to be a permanent magnet. And all because the magnetic domains in the ferromagnetic material are largely aligned.
Why heat demagnetised the steel?
A piece of metal can be magnetized if the atoms of which it is composed are magnetic, and they have aligned their north-south poles to point in the same direction. Heat increases atomic vibration and will cause these atoms to lose their alignment and point in all different directions, so that their atomic magnetic fields will not combine to form one large magnetic field.
What is an example of magnetic field?
The atmosphere of the earth is a magnetic filed
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.
What is an example of a magnetic material?
Steel is a magnet material, but not all metals are magnetic, like Aluminum.
Why are some objects attracted to magnets while other objects are not?
Some objects are not attracted by magnets because they are not metalic. If the Magnet just attracts metalic minerals, definitely only metalic are attracted and not non-metalic..
