A magnet can lose its strength due to exposure to high temperatures, physical impact or dropping, exposure to strong magnetic fields in the opposite direction, or age-related demagnetization over time.
I do not know if they can lose their magnetic energy or not.
Hardly worth spending the time to type that answer then, eh?
If you magnetise e.g. an iron bar by striking it with a magnet, and then orient it (say) East-West and it it hard with a hammer, it will have lost some of its magnetism. Well, it won't have 'lost' it exactly, but it will have become more-or-less re-magnetised in a different orientation which has the same effect.
That is only a partial answer and not quantitative (but at least more informative than the first attempt) but this is a serious and interesting question and deserves a more fulsome and authoritative answer. Sorry I cannot provide it, but I bet Google could ...
Magnets can weaken over time because the magnetic domains comprising the substrate become misaligned. Instead of pointing all in one direction, as they do in a "good" magnet, they point in different directions, with the result that the overall magnetic force is diminished.
Magnets do lose a small fraction of their power over time. To help a magnet retain their power for as long as possible, keep them away from high temperatures and power sources.
Magnets lose their magnetism when they are dropped many times, heated over a flame or hammered many times

Does heating up a magnet make it stronger?
Heating up a magnet can temporarily increase its magnetic strength by aligning its magnetic domains. However, once the magnet cools down, it will return to its original magnetic strength. Heating a magnet beyond its Curie temperature can cause it to lose its magnetism altogether.
Is the south pole of a magnet stronger than the north pole?
Not if the magnet is symmetrical, and you define 'strength' in terms of flux density.Yes because it has a stronger attraction rate.there is no stronger or weaker for a magnet
How does the magnet works on cold and hot temperature and what important idea.?
The strength of a magnet can be affected by temperature. In cold temperatures, a magnet's strength increases, while in hot temperatures, the strength decreases. This is because temperature affects the alignment of atoms within the magnet, which in turn affects the magnet's ability to produce a magnetic field. An important idea to note is that extreme temperatures can demagnetize a magnet altogether.
When magnet is dipped or kept in water does it lose its power of attraction?
No, a magnet does not lose its power of attraction when it is dipped in water. The magnetic field of the magnet remains intact in water and it can still attract objects.
Why can a magnet be demagnetised by hammering it?
Hammering a magnet can disrupt the alignment of its magnetic domains, causing them to become disordered and reducing the overall magnetic field strength. This process can demagnetize the magnet as the domains lose their alignment and no longer exhibit a strong magnetic pull.
Does temperature have an effect on magnet strength?
Yes, temperature can have an effect on magnet strength. High temperatures can cause magnets to lose their magnetic properties, while low temperatures can sometimes enhance their magnetic strength. This is known as the Curie temperature, above which a magnet will lose its magnetism.
Does cold temperatures affect the strength of a magnet?
Extreme cold temperatures can affect the strength of a magnet by causing it to lose some of its magnetism temporarily. However, once the magnet returns to a warmer temperature, its strength should return to normal. Tempering and material composition can also impact a magnet's ability to withstand cold temperatures without losing strength.
How do you change the temperature of a magnet?
You can change the temperature of a magnet by heating or cooling it. When you heat a magnet, it can lose its magnetism, while cooling a magnet may increase its magnetic strength. Extreme temperatures can also affect the properties of a magnet, so it's important to be cautious when altering its temperature.
Does heating up a magnet make it stronger?
Heating up a magnet can temporarily increase its magnetic strength by aligning its magnetic domains. However, once the magnet cools down, it will return to its original magnetic strength. Heating a magnet beyond its Curie temperature can cause it to lose its magnetism altogether.
Which temperature of Magnets affects the magnets strength?
The Curie temperature is the temperature at which magnetic materials lose their magnetic properties. If a magnet is exposed to temperatures beyond its Curie temperature, it will lose its magnetism. However, at lower temperatures, the strength of a magnet tends to increase due to a decrease in thermal motion among its magnetic dipoles.
Does temperature affect the strength of a magnet is it chemical science?
NO!!! the strength of magnet is not affected by temperature
Dropping or heating a magnet will not weaken it because the domains will stay in alignment?
When you drop or heat a magnet, the domains may temporarily lose alignment, but once the magnet stops moving or cools down, the domains will realign and the magnet's strength will return. Dropping or heating a magnet will not permanently weaken it.
Does magnet size affect the strength of a magnet?
Yes it does!
What affects the strength of a magnet's pull or push?
The strength of a magnet's pull or push is influenced by factors such as the material the magnet is made of, its size, and the distance between the magnet and the object it is attracting or repelling. Additionally, the shape of the magnet and any magnetic fields nearby can also affect its strength.
When does the magnetic domain in a magnet produce a weaker magnet?
When the external magnetic field is removed, the magnetic domain in a magnet can produce a weaker magnet due to randomization of the magnetic moments within the domains, causing them to lose alignment. This results in a decrease in the overall magnetic field strength of the magnet.
Why does a magnet lose its' magnetism by hammering and heating?
When a magnet is hammered or heated, it disrupts the alignment of its magnetic domains, causing them to become disordered. This disorderliness reduces the overall magnetic field strength of the magnet, resulting in a loss of magnetism.
How can the strength of a scrap heap magnet vary?
The strength of a scrap heap magnet vary depending on the strength of the current or number of "turns" in its primary coil. Increasing either or both of these makes the magnet stronger.
