For such a broad question, magnets may be used for many situations and are popular assistants to people for everyday managements. One obvious example involves the refrigerator:
Magnets are used for holding up pictures, lists, advertisements, and other personal visuals onto the fridge.

Which method is used to separate aluminium filings?
magnetization
Is hammering a method of magnetization?
Yes, hammering is a method of magnetization known as mechanical magnetization. When a ferromagnetic material is struck, the impact can align some of its magnetic domains in the direction of the applied force, enhancing its magnetization. This process is often used in various applications to temporarily or permanently magnetize materials. However, it is not the most efficient method compared to others like electrical or thermal methods.
How could you test the effects of heating and cooling on the magnetization of a bar magnet?
To test the effects of heating on magnetization, heat the bar magnet to a specific temperature and measure its magnetization using a magnetometer. To test the effects of cooling, cool the bar magnet to a specific temperature and again measure its magnetization. By comparing the magnetization measurements before and after heating or cooling, you can observe any changes in the magnetization properties of the bar magnet.
What is not a method of magnetization?
One method of magnetization that does not exist is through gravitational force. Magnetization can occur through methods such as electric current, contact with a magnetic field, or exposure to a strong magnetic material.
Why an ac supply is not used to magnetize a bar of steel?
An AC supply is not used to magnetize a bar of steel because the alternating current continuously changes direction, causing the magnetic field to fluctuate. This results in the magnetization being ineffective, as the steel would not retain a stable magnetic orientation. For permanent magnetization, a direct current (DC) supply is preferred, as it creates a steady magnetic field that can align the domains in the steel and maintain the magnetization.
Give the reason why the magnetization curve starts above the origin?
The magnetization curve starts above the origin due to the presence of residual magnetism or remanent magnetization in magnetic materials. This initial magnetization, known as coercivity, occurs because some magnetic domains remain aligned even after the external magnetic field is removed. As a result, the material retains a certain level of magnetization, leading to a non-zero starting point on the curve. Additionally, this behavior reflects the material's magnetic history and intrinsic properties.
What are the factors affect the shape of the magnetization curve?
there is no factors
Does the earth's minerals magnetization is the way to earth rotate or fullmoon effect?
Your question is not clear and it is difficult to understand. However the earth's magnetization is not affected by rotation or the full moon.
What is the noun for magnetize?
The noun forms of the verb to magnetize (magnetise) are:magnetizer (magnetiser)magnetization (magnetisation)the gerund, magnetizing (magnetizing)A related noun form is magnet.
What is the significance of the magnetization partition function in the study of magnetic systems?
The magnetization partition function is important in studying magnetic systems because it helps calculate the average magnetization of a system at a given temperature. It provides insight into how magnetic materials behave and how they respond to external influences, such as temperature changes.
Is there limit to magnetization?
no cuz it can be aas weak or as strong as you want it to be
Why is magnetization of iron a physical change happen?
Magnetization of iron is considered a physical change because it involves the alignment of magnetic domains within the material without altering its chemical composition. When exposed to a magnetic field, the domains align in the direction of the field, resulting in magnetization. This process is reversible; removing the magnetic field can lead to a loss of magnetization, demonstrating that the intrinsic properties of the iron remain unchanged. Thus, the change is physical rather than chemical.
