How can a permanent magnet be demagnetized effectively?
A permanent magnet can be demagnetized effectively by subjecting it to high temperatures or strong magnetic fields in the opposite direction of its magnetization. This disrupts the alignment of its magnetic domains, causing it to lose its magnetism.
How can a permanent magnet be demagnetized?
A permanent magnet can be demagnetized by exposing it to a strong external magnetic field in the opposite direction of its original magnetization, heating it above its Curie temperature, or subjecting it to physical impacts that disrupt its magnetic alignment.
What is a temporary magnet called?
A temporary magnet is called a soft magnet. It can be easily magnetized and demagnetized, unlike a permanent magnet that retains its magnetism for a longer period of time.
How can a magnet be demagnetized using another magnet?
When a magnet is exposed to a strong magnetic field from another magnet, the alignment of its magnetic domains can be disrupted, causing it to lose its magnetism and become demagnetized.
What is a hard magnet?
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.

How is a permanet magnet destroyed?
Physical damage, exposure to extreme heat, or exposure to strong magnetic fields can cause a permanent magnet to lose its magnetism. Once a permanent magnet is demagnetized, it is very difficult to restore its original magnetic properties.
How can a magnet be demagnetized using another magnet?
When a magnet is exposed to a strong magnetic field from another magnet, the alignment of its magnetic domains can be disrupted, causing it to lose its magnetism and become demagnetized.

What will happen to the magnet if you put some electricity on it?
it will be demagnetized
How long does it take for a magnet to lose its power and become demagnetized?
The time it takes for a magnet to lose its power and become demagnetized depends on factors like the material of the magnet and how it is used. In general, permanent magnets can retain their magnetism for a long time, even decades or centuries. However, external factors like high temperatures, strong magnetic fields, or physical damage can cause a magnet to lose its power more quickly.
Is a permanent a magnet?
A permanent magnet is a magnet which will keep its magnetism for a very long time and is difficult to change. No, As I think a permanent magnet means they have abilities to hold the magnetism when they are magnetized. Such as Alnico permanent magnets, but in fact, they can be demagnetized,such as high temperature, hit each other,pulse waves, out magnetic field influence...What's more, different permanent magnetic material, have different abilities on holding magnetism,they can be used in different environments. you can find some details from some manufacturers website, to learn some knowledges.
Why soft iron is used for making a permanent magnet?
Soft iron is not used for making permanent magnets; instead, it is used as a temporary magnet due to its high magnetic permeability and ability to be easily magnetized/demagnetized. Permanent magnets are typically made from hard magnetic materials like neodymium or ferrite, which can retain their magnetism for a long time.
Why is it that permanent magnets can never be demagnetized?
Permanent magnets can never be demagnetized because they are made of materials with strong magnetic properties that align in a way that maintains their magnetic field over time.
Different between temporary magnet and Parmanent magnet?
A temporary magnet can be magnetized or demagnetized easily, while a permanent magnet retains its magnetization over a long period of time. Temporary magnets are usually made of soft magnetic materials like iron, while permanent magnets are made of hard magnetic materials like neodymium or ferrite. Temporary magnets require an external magnetic field to maintain their magnetism, whereas permanent magnets do not.
