How long do cheap magnets last compared to more expensive ones?

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.

∙ 10y agoThe length of time that the cheap metal and the more expensive magnets last is about the same because both perform the job of holding material with magnetic force. It is the duration of the holding power that differs because the more expensive magnet is manufactured with more magnesium than the less expensive magnet. Therefore, the expensive magnet has a stronger holding power but there is no difference in the duration of how long the two types of magnet lasts.

∙ 14y agoIf you mean a temporary magnet, that depends on the material your temporary magnet was made of, and also the type of material the magnet was made of and it's magnetic strength.

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 do not quote me on that.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.

How can a magnet be used to separate one material from another?
a mixture of iron filings and sandif we have a mixture of sand salt and iron first the iron well be separated with the magnet then the remaining mixture will be put in water where the sand will goes to the bottom. at last the water will be evaporated and the salt remains
What are the pros of non-renewable?
The advantage of non renewable energy, is it's easy and cheap to use. There is no better way to store transfer and use energy than gasoline for powering motor vehicles. It's quick to pump fossil fuel into a car. Its stable in the tank and a gas tank hold quite a bit, and a gasoline powered car is cheap to manufacture. * Coal is a ready-made fuel. * It is relatively cheap to mine and to convert into energy. * Coal supplies will last longer than oil or gas * Oil is a ready-made fuel. * Relatively cheap to mine and to convert into energy * It is a relatively cheap form of energy. * It's a slightly cleaner fuel than coal and oil. * Gas is a ready-made fuel. * Nuclear has a small amount of radioactive material produces a lot of energy. And raw materials are relatively cheap and can last quite a long time. * It doesn't give off atmospheric pollutants. * Biomass is a cheap and readily available source of energy. and If the crops are replaced, biomass can be a long-term, sustainable energy source, but Biomass is actually considered renewable as plants are always growing. * Wood is a cheap and readily available source of energy. If the trees are replaced, wood burning can be a long-term, sustainable energy source
What is carbon-14 used for?
Carbon-dating. This is a process by which the proportion of carbon-14 in an organism is compared to the proportion know to be in the environment the carbon came from. By comparing the proportions, a scientist can determine the amount of time since the last replacement of the carbon-14, and thus give a rough time of how long ago the organism died.
What is the difference between a cheap hardrive compared to a expensive one?
How long it will last and performance.
Which nail polish last longest expensive or cheap test.?
expenisive
Why don't cheap pens last as long as expensive pens?
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.
What is the main disadvantage of a cheap paint job for your car as opposed to an expensive one?
The disadvantage for a cheap paint job for a car is that the paint does not last, because cheap paint for cars can wear off. As for expensive paints, you don't have to worry about the paint wearing off.
Are cheap tires made of a lesser quality rubber than expensive tires?
Yes,cheap tires are most probably of lesser quality rubber than expensive ones. Expensive tires last longer and more reliable than it's cheaper counterpart.
What are the disadvantages of buying a cheap dining table and chairs over a more expensive set?
A cheap dining table will scratch easily, the chairs will probably not be as sturdy. A more expensive one will usually have a classier design and will last a lot longer.
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.
Do magnets last forever?
yes
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
