A permanent magnet will retain its magnetism unless it is affected by a strong outside magnetic or electrical force, or elevated temperatures. If they are not exposed to any of these conditions, permanent magnets will lose magnetism on their own, however this degradation is very slow, on the order of one percentage point every ten years or so.

What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
What are the strongest magnets other than super conducting magnets?
NdFeB neodymium magnets are the strongest magnet with the highest magnetic performance and coercive force in the world. Neodymium NdFeB magnet has excellent magnetic property and extremely strong for its small size. NdFeB magnet is more sensitive to temperature changes, ranging from 0.10%/°C - 0.13%/°C. NdFeB magnet is the permanent magnets with highest maximum energy product. Over the last 10 years, due to high ratio of performance over price of the NdFeB magnet, NdFeB magnet has become extremely popular in almost all high technology applications that require high performance magnets, motors, sensors, computers, communications, medical equipment, meters, home appliances and so on.

The last glaciation, known as the Last Glacial Maximum (LGM), occurred approximately 20,000 years ago during the Pleistocene epoch. It was a period of extensive ice coverage and cooler temperatures compared to the present day.
What fossil fuel probably has enough to last?
Natural gas is estimated to have enough reserves to last for several decades at current consumption rates, making it a fossil fuel that is likely to last longer compared to oil and coal. Additionally, advancements in technology and exploration may further increase its accessible reserves in the future.

Because cheap pens are cheap, they aren't as reliable in general. Expensive pens are usually made more carefully and with better material.
Does expensive or cheap batteries last longer?
the cheeper batteries tend to only last 2.5 hours in a high energy circuit but the expensive last 20hrs+ my bet would be on the expensive so dont waste your money on cheep
What is difference in cheap tools and expensive tools?
Just because something is more expensive doesn't always mean it is more reliable. However, many cheap tools don't last very long. The more expensive ones usually last a lot longer and are worth buying in the long run.

Do cheap automotive batteries last as long as more expensive batteries?
No they don't. The slogan goes " you get what you pay for " and this is one of those instances. The better batteries have better cells and they can last a lot longer than a cheap battery.
Is it cheaper to buy a last-minute ticket at the airport?
No, it is usually more expensive to buy a last-minute ticket at the airport compared to purchasing in advance.
Do cheap automotive batteries last as long as expensive brands?
On average, the cheap ones will do the job, but over time you can argue for more leading brands. The reason being the expensive brands usually have more reliability, then your second name. Note that not all expensive brands are the same in comparison, but they are about the same in battery life.
How much do stunt pegs weigh?
it all depends on the type you have you can get cheap one which expensive or good brand on that are light and last a while
