Domains in magnetized materials are all aligned in one direction - those in un-magnetized objects are arranged randomly.
One way to tell if a substance is magnetized to hold something metal next to it. Some other tools are listed on this site: http://www.lessemf.com/dcgauss.html
Magnetization does not affect the mass of the material being magnetized. All the magnetizing field does is align the magnetic domains of the material being magnetized. No matter or mass is added, or "created out of energy" or the like. Nothing changes except the orientation of magnetic domains within the material being magnetized.
In a magnetized substance, domains are small regions where magnetic moments align in the same direction. These domains help create the overall magnetic properties of the material by allowing it to be magnetized and retain its magnetism. When external magnetic fields are applied, domains can collectively align to strengthen the material's magnetic field.
The final substance when iron is magnetized remains as iron. Magnetization does not change the fundamental composition of the iron material, but rather aligns the magnetic domains within the iron to create a magnetic field.
Ferromagnetic substances are materials that have strong magnetic properties and can be magnetized. They include iron, nickel, and cobalt. These materials can retain their magnetic properties even after the external magnetic field is removed.
Yes, nickel can be magnetized.
No, lead cannot be magnetized.
No, copper is not naturally magnetized.
In the high energy state of atoms in a magnetized substance, the magnetic moments of the atoms align parallel to the applied magnetic field. This alignment is the result of the energy minimized configuration, where the atoms' magnetic moments align in the direction of the magnetic field to reduce the overall energy of the system.
The not magnetized rod will be attracted by both of the magnetized rods.
Yes, if a nail is made of steel, it will will not be magnetized unless it is magnetized by a magnet by being hit.
