What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
Is aluminum sheet metal magnetic?
No, aluminum sheet metal is not magnetic.
What is happening inside a metal to make it magnetic?
Inside a metal, the atoms align in a specific way, creating magnetic domains. When an external magnetic field is applied, these domains align in the same direction, making the metal magnetic. This alignment creates a magnetic field around the metal.
Why is metal magnetic?
Metal is magnetic due to the alignment of its electrons in a way that creates a magnetic field. This alignment allows the metal to be attracted to magnets or generate its own magnetic field. The presence of unpaired electrons in the metal's atomic structure also contributes to its magnetic properties.
What type of metal is not magnetic?
One example of a non-magnetic metal is aluminum. It does not have magnetic properties because its atoms do not align in a way that creates a magnetic field.
How many is retentivity of soft iron?
Retentivity, or magnetic retentivity, refers to the ability of a material to retain magnetization after an external magnetic field is removed. For soft iron, the retentivity is relatively low compared to hard magnetic materials; it typically measures in the range of a few milliTesla. This property makes soft iron ideal for applications like electromagnets and transformers, where rapid magnetization and demagnetization are required.
What material have high retentivity?
Materials like iron, nickel, and cobalt have high retentivity, which means they can retain a significant amount of magnetization even after the magnetic field is removed. This property makes them useful in applications such as permanent magnets and magnetic storage devices.
What is difference between residual magnetism and retentivity?
Residual magnetism and remanence are the same thing. The term residual magnetism is often used in engineering applications. Both terms describe the magnetization, and measure of that magnetism, left behind in a ferromagnetic material after the external magnetic field is removed.
Distinguish between the magnetic properties of iron and steel?
The magnetic properties of iron are high susceptibility and low retentivity. It means that it is easier to magnetize but also loses magnetism easily. The properties of steel are the opposite of iron.
What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
Is aluminum sheet metal magnetic?
No, aluminum sheet metal is not magnetic.

What is the main metal in steel and it is also magnetic?
the main metal is iron and yes it is magnetic
Why is metal magnetic?

Is megnet metal or non metal?
Metallic or non-metallic elements can be magnetic.
Is platinum magnetic?
No, platinum is not magnetic. It is a non-magnetic metal and does not exhibit magnetic properties.
Can you deflect metal with magnetism?
Yes, metal can be deflected by magnetism through the use of a magnetic field. When a metal object interacts with a strong magnetic field, it can be pushed or pulled in a certain direction due to the magnetic forces at play.
