The effect of temperature on magnetization?
Each material which can be magnetized has a material specific, so called Curie temperature. Above this specific temperature the material will lose its magnetism and the ability to be magnetized. Returning below this temperature, the material regains its magnetic properties.
What is domain in magnet?
A magnetic domain is a region of uniform magnetization within a material.
What is remanence?
The magnetization left behind in a ferromagnetic material (e.g. iron) after an external magnetic field is removed.
Does magnetization affect the mass of the substance magnetized?
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.
What is A magnetic substance can also be made into a?
If you are talking about a non-magnet item then the item will become a magnet for a period of time. Changes in heat, how much it is used, or time can disable the magnet. Magnet!
What is magnetization of iron?
the process of converting iron to a permanent magnet is called magnetization. As iron is a ferro magnetic material it is magnetized by applying strong magnetic field across it , this makes the alignment of all the magnetic dipoles present in iron in the same direction .Even after the external magnetic field is removed they retain their arrangement , thus it becomes a permanent magnet
Which magnetic material can retain permanent magnetization?
False permanent magnets can but electromagnets need a running current A+

What is Magbetometer?
A magnetometer is an instrument that measures magnetic forces and the magnetization of magnetic material. A magnetometer can be found in cell phones and metal detectors.
What is remanence?
The magnetization left behind in a ferromagnetic material (e.g. iron) after an external magnetic field is removed.
What is the significance of hysteresis?
Hysteresis is the delay between an observed outcome and the quantity of change applied.When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. It must be driven back to zero by a field in the opposite direction. If an alternating magnetic field is applied to the material, its magnetization will trace out a loop called ahysteresis loop. The lack of retraceability of the magnetization curve is the property called hysteresis and it is related to the existence of magnetic domains in the material. Once the magnetic domains are reoriented, it takes some energy to turn them back again. This property of ferrromagnetic materials is useful as a magnetic "memory". Some compositions of ferromagnetic materials will retain an imposed magnetization indefinitely and are useful as "permanent magnets". The magnetic memory aspects of iron and chromium oxides make them useful in audiotape recording and for the magnetic storage of data on computer disks.Variations in Hysteresis CurvesThere is considerable variation in the hysteresis of different magnetic materials.
What are the small individual areas within a magnet called?
magnetic domains. itdescribes a region within a magnetic material which has uniform magnetization. This means that the individual magnetic moments of the atoms are aligned with one another and point in the same direction. Below a temperature called the Curie temperature, a piece of ferromagnetic material undergoes a phase transition and its magnetization spontaneously divides into many tiny magnetic domains, with their magnetic axes pointing in different directions. Magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron. The regions separating magnetic domains are called domain walls where the magnetisation rotates coherently from the direction in one domain to that in the next domain.
Does magnetization affect the mass of the substance magnetized?
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.

Two matierials with a weak magnetic domain?
A magnetic domain refers to a region within a magnetic material that has uniform magnetization. Two materials with a weak magnetic domain are bismuth and pyrolytic carbon.
