What is The temperature which magnetic material can retain a permanent magnetization is called?
The temperature at which a magnetic material can retain permanent magnetization is called the Curie temperature (or Curie point). Above this temperature, the material loses its permanent magnetic properties and becomes paramagnetic, as the thermal energy disrupts the alignment of magnetic domains. Below the Curie temperature, the material can maintain a stable magnetization.

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.
A material that holds its magnetic properties without losing them is a?
ferromagnetic material, such as iron, nickel, or cobalt. These materials can retain their magnetization even after the external magnetic field is removed.
What happens above Curie temperature?
Above the Curie temperature, a ferromagnetic material loses its permanent magnetization and becomes paramagnetic. This occurs due to thermal energy disrupting the alignment of magnetic domains within the material, causing it to lose its magnetic properties.
When a magnet is placed near a magnetic material the magnetic material becomes a magnet . what is the name of this process?
The process by which a magnetic material becomes magnetized when placed near a magnet is called "magnetization." During this process, the magnetic domains within the material align in the direction of the external magnetic field, resulting in the material exhibiting its own magnetic properties. This effect is temporary for most materials, but some can retain magnetization, making them permanent magnets.
Why the magnitude of the saturation magnetization decreases with increasing temperature for ferromagnetic material?
As temperature increases, thermal energy disrupts the alignment of magnetic moments in ferromagnetic materials. This causes a decrease in the alignment of magnetic domains, leading to a decrease in the overall saturation magnetization.
The temperature below which magnetic material can retain a permanent magnetization is called?
Curie temperature.

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

A piece of magnetic material that retains its magnetic properties after it is removed from a magnetic field?
A material that retains its magnetic properties after being removed from a magnetic field is called a permanent magnet. These materials are able to maintain their magnetization due to their atomic or molecular structure that allows them to have a permanent magnetic field. Common examples include materials like iron, cobalt, and nickel.
Which magnetic material can retain permanent magnetization?
False permanent magnets can but electromagnets need a running current A+
Define intensity of magnetization?
Intensity of magnetization is a measure of the magnetic moment per unit volume of a material when it is placed in a magnetic field. It quantifies the extent to which a material can become magnetized in response to an external magnetic field.
What is thero-magnetic?
Thermo-magnetic refers to the interaction or effect of temperature on the magnetic properties of a material. Changes in temperature can influence the magnetic behavior of materials, causing variations in their magnetic properties such as magnetization, susceptibility, or coercivity. This effect is commonly observed in magnetic materials and is an important consideration in various applications such as magnetic storage devices and temperature sensors.
What is domain in magnet?
A magnetic domain is a region of uniform magnetization within a material.
What is magnetic hysteresis?
Magnetic hysteresis is the phenomenon where the magnetization of a material depends not only on the current magnetic field, but also its history. When the magnetic field is applied and then removed, the material retains some magnetization, showing a lag or "memory" in its response to changing magnetic fields. This results in the characteristic hysteresis loop observed in magnetic materials.
