the temperature depends on what material you are using such as iron. it als depends on the size of the magnet

What temperature demagnetizes a magnet?
Does the Temperature of a magnet affect its strength
What did Pierre Curie invent?
Pierre Curie invented the most Curie Point. The Curie Point is a point at which ferromagnetic substances lose their ferromagnatism. He and his wife's research also led to many important discoveries in modern physics and chemistry.
Does water temperature affect magnets in water?
yes because the magnet will reach its curie temprature and loose stregth
How do you destroy a magnet?
The same way you destroy anything else. melt it in a furnace is the only way because if you chop it one end will be south and the other will be north If you mean "How do you remove the magnetism from a permanent magnet?" There are several ways. You can heat it past its Curie Point. For iron that is about 800C. Stroking one magnet with another in a random fashion will sometimes work. Hammering it will usually work.
Does temperature affect magnetism?
The short answer:Yes.The longer answer for those curious ones: Yes, temperature affects the strength of a magnet. Colder temperatures will permit the magnetic field strength to increase a bit and hotter temperatures will decrease it a bit.What happens at really high temperatures?There is a point called the Curie point or Curie temperature (Tc) at which the magnetic properties disappear altogether. This temperature varies from material to material. The material's magnetic domains are no longer "held in place" by the metallic crystal matrix when the Tc is exceeded. The atoms have too much kinetic energy and a random distribution of alignments of the domains will occur. Bye bye magnetism, hello paramagnetism.The effects can be demonstrated by a simple experiment.You need a bar magnet, a thin rope and a hand full of carpet tacks. Secure one end of the rope to the magnet. (so that you do not burn yourself in experiment later.)Freeze the magnet. Pick up some tacks. Take them off and count them. Record the data.Drop the magnet in boiling water. Pick up tacks again. Take them off and count them. Record the data. Compare the data. Repeat a few times. Compare the data from all runs. You should find that the magnet is stronger the colder it is.
Why do magnets react to temperature?
Well, what I know is that when a magnet reaches a certain temperature,it hits a Curie Point. That is a really high temp that makes a magnet lose it's magnetic properties.
Which of the following can be done to demagnetize a permanent magnet?
heating the magnet past the Curie point
What temperature demagnetizes a magnet?
Does the Temperature of a magnet affect its strength
Does the temperature of a magnet effect its magnetic field?
Not until the magnet reaches its "Curie point" or temperature. Then magnetic activity ceases.
How heating demagnetises a magnet.?
A magnet works because the atoms of a magnet are all aligned in only a single uniform direction, in most cases due to the direction of north to south.Heating a magnet causes the alignment to be disturbed and be misaligned, thus losing its magnetic power.The temperature at which a heated magnet loses its magnetism is called the Curie Point named after Pierre Curie husband of Marie Curie.
How can you destroy a magnet?
If you take a permanent magnet and heat it up past the Curie temperature (or Curie point, Tc) and cool it, the magnetic domains in the magnet, which were aligned when it was made, will become randomly oriented. When the "magnet" cools, its magnetic properties will have "disappeared" and the you'll have a piece of metal alloy. If you like, you can make a new magnet out of your hunk of metal by heating the metal past the Curie point again, applying a static magnetic field to it, and then cooling it back down in the presence of the magnetic field. That's the way the magnet was manufactured and made into a magnet to begin with.
How to cause a magnet to lost its magnetic power?
A magnet can lose its magnetism if exposed to high temperatures. If heated above the point called the Curie temperature, a magnet will lose its magnetism.
Does the strength of a magnet become affected when subjected to different degrees of hot and cold temperatures?
A. A magnet has a Curie Point, a temperature beyond which it is no longer a magnet. Identified by Marie Curie. This property is used in items such as toaster timers. As far as I know there is no low temperature limit.
Why Is earth not a permanent magnet?
The simplest evidence that the Earth is not a permanent magnet is given by the fact of the polar wander. But more fundamentally, the interior of the Earth is far too hot for a magnet to retain its field. Pierre Curie worked on many things, and the loss of magnetism at elevated temperatures was one of his discoveries, and is known as the Curie point for a magnetic material. Importantly, the material cannot contain a magnetic field above this point. Thus a transformer will lose its abilities above the Curie point of the (iron) laminations inside.
What is the definition of a magnet?
A permanent magnet is a magnet that has been manufactured to "permanently" hold its magnetic field. Ferromagnetic material of a desired shape is heated above its Curie point, exposed to a large electromagnetic field, and cooled slowly while being held in that field. This allows the magnetic domains in the material to align themselves with the field of the electromagnet. Further, when the material cools below its Curie point, the magnetic domains will remain in the position they are in when the electromagnet is shut off. The magnet is now a permanent magnet; the magnet "holds" the magnetic field "imprinted" on it.
How does temperature effect magnets?
I did a science fair experiment on this last year. It is found that magnets that have higher temperature were weaker. to support this claim you should research about the "curie point" which basically says that this is a temperature ( really hot) where the magnet will lose its magnetic properties.
Why is the Curie point important?
The Curie Point is named fro Pierre Curie, not Marie Curie. It is the point above which a material loses its spontaneous magnetism.
