Hi I am not an expert but the answer is complicated and it depends on what you are trying to achieve if you need a magnetic field to operate in high temperatures its one thing, if you need a magnet to loose its strength at a specific temperature its another thing you can ask laboratories to mix materials that attract magnets in different proportions and change the temperature at which they stop working here are the temperatures

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.
Does temperature have an effect on magnet strength?
higher the temperature, lower is the magnetic strength..
Does temperature affect the strengh of a magnet?
Yes, it does due to the magnetic force coming from the magnet. After a period of time the magnet that is in lower temperature increases while higher temperatures decrease.
Is monel magnetic?
Monel Information from American Special Metals, Corp. www.AmericanSpecialMetals.comAlloying elements other than cobalt and iron in solid solution in nickel lower the Curie temperature. Sufficient copper is present in Monel to lower the Curie temperature so that although Monel is usually slightly magnetic at room temperature, it will become non-magnetic when warmed mildly. When the alloy contains about 1.25% Si, it is non magnetic at room temperature. A Si content of 4% lowers the Curie temperature to approximately -70F. The magnetic properties are not affected greatly by cold work or thermal treatment.
What is the definition of a permanent magnet?
The permanent magnet generator is a synchronous machine where the rotor windings has been replaced with permanent magnets. This eliminates the excitation loses in the rotor, which otherwise typically represent 20-30% of the total generator loses. The reduced losses also give a lower temperature rise in the generator, which means that a smaller and simpler cooling system can be used. The temperature reduction in the rotor also reduces the temperature in the bearings, improving reliability by increasing the lifetime of the bearing and bearing grease.
How does distance affect the strenght of the force of gravity?
it is like a magnet to metal and the sun is our magnet to the planets but inertia is the thing that keeps it away from our magnet the sun The farther apart two objects are, the lower the gravitational force between them, so gravity gets weaker with distance. To be specific, it decreases by the square of the distance. So if you double the the distance, the force of gravity is 1/4 as strong. If you triple the distance, the force is 1/9 as strong, and so on.
What is a strong wind in the lower stratosphere?
Jet Stream The main jet streams are located near the tropopause, the transition between the troposphere (where temperature decreases with altitude) and the stratosphere(where temperature increases with altitude)
Taking heat out of the air will do what to the temperature?
Removing heat from the air will lower its temperature.
What effect does adding a solute have on the boiling of solution?
The solution freezes at a lower temperature and boils at a higher temperature.
Will temperature be higher or lower in a mountain?
it is lower temperature when you to mountain,because its cold there
What will happen if the ignition temperature is lower than the room temperature?
If the ignition temperature of a substance is lower than the room temperature where it is, then that substance ignites.
Are the temperature of the moon are higher or lower than the earth?
the temperature of the earth is lower than the Earth.
