What else can I help you with?
Is Lead can be used for absorbing a magnetic field?
Yes, the heavy aprons used in the X-RAY room are lined with lead.
A cluster of billions of atoms that all have magnetic fields lined up in the same way is known as a?
A cluster of billions of atoms that all have magnetic fields lined up in the same way is known as a ferromagnetic material. This alignment creates a strong magnetic field within the material, making it magnetically responsive.
Why a piece of iron doesn't behave as a magnet?
A piece of iron doesn't behave as a magnet on its own because the magnetic domains within the iron are not aligned to create a magnetic field. In order for the iron to become magnetized and exhibit magnetic properties, an external magnetic field must be applied to align the domains.
What magnets act like several combined bar magnets?
A magnetic field surrounding a bar magnet behaves similarly to a combination of multiple smaller bar magnets lined up in a row. The overall magnetic field is the sum of the individual fields created by each smaller magnet. This concept helps in understanding the behavior of complex magnetic systems with multiple magnetic elements.
True or false in a magnetzed material most of the domains are lined up in the same direction?
True. In a magnetized material, most of the domains are indeed aligned in the same direction, creating a magnetic field.
Matter in which particles line up pole to pole?
Ferromagnetic materials exhibit pole-to-pole particle alignment. This alignment is primarily observed in materials where the magnetic moments of individual atoms align parallel to each other to produce a net magnetic field, such as in iron, cobalt, and nickel. Ferromagnetic materials can retain their magnetization even after an external magnetic field is removed, making them suitable for applications like permanent magnets and data storage.
How have switches in the location of earths magnetic poles been determined?
Magnetism leaves particles in molten metals lined up with north and south poles (magnetic poles, not the Earth's poles). Over time different layers of rock show that the N-S and S-N poles have switched, with S pointing in one direction and S pointing in a different direction depending on the age of the rock.
Why are magnetic domains lined up?
Magnetic domains align to minimize energy. When aligned, the magnetic moments within a domain reinforce each other, creating a stronger overall magnetic effect. This alignment is driven by the exchange interaction and can be influenced by external magnetic fields.
What makes a magnets magnetised?
The simple answer: ferro-magnetic materials have small regions that are magnetic while the whole piece is not. A magnet has had these regions lined up. Quantum physic answer: The electrons orbiting the nucleus of the atom induce a very small magnetic field. Much like an electromagnet. For most atoms this force is negligible compared to other forces in a system. Some heavier atoms that have more electrons will, for some instant, have multiple orbits that line up (or nearly line up). This creates a stronger magnetic field. For that instant the atom acts as a very tiny magnet adding to the magnetic field of "real" magnet. Each of these tiny magnets must the be aligned, usually with a strong electromagnet.
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.
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.
Can you apply magnetic field on super conductor?
Yes. One application of a magnetic field on a super conductor is quantum locking. Imagine the field lined of magnet penetrating an object. Now transform that object into a super conductor (i.e. super cool a substance that is not a super conductor at room temp into a super conductor by cooling it to a point where it is). That object is now quantum locked on the field lines and will tend to remain in a similar position without outside influence, besides the magnet, of course. It is such a principle that mag-lev trains that use superconductors operate on.
