Temperature and Neodymium Magnets If you start at room temperature (20°C) and get colder, the strength of the magnet increases by a small amount. Below about -125°C, the strength then drops much more quickly. Still, even at temperatures near absolute zero, there is still a good deal of magnetic strength left.

- Heating a material above its Curie temperature will destroy its permanent magnetic properties, yes. The magnetic dipole moment of a metal is what makes it magnetic. Above a material's Curie temp, those moments get scrambled and they don't align in the same way once it is cooled.

Heat Treating's Strength, Costs In normalizing treatments, ferrous alloys are heated to a temperature above the transformation range and air-cooled to room temperature, creating a pearlitic microstructure. This gives the casting a higher hardness and strength than is obtained in the as-cast or annealed condition.

Heat Distortion Temperature (softening temperature) These Charts show the thermal deformation temperature and the softening temperature (called the “Vicat softening temperature”) of major plastics. The heat distortion temperature is the temperature when the test piece placed in the heat medium with bending load applied reaches a specified deflection as temperature rises. The Vicat softening temperature is defined as the temperature where the needle shaped penetrator sinks into the test piece to a specified depth as temperature of the heating medium rises and specified vertical load is applied to the test piece.

- Magnets are made by exposing ferromagnetic metals like iron and nickel to magnetic fields. When these metals are heated to a certain temperature, they become permanently magnetized. It's also possible to temporarily magnetize them by using a variety of methods you can try safely at home.

- However, a good method to qualify the performance of magnetizing coils is not common. Industry specifications, end users and manufacturers often improperly qualify a magnetizing coil’s “strength” using “ampere•turns” (amp•turns) instead of the more appropriate “gauss field strength unit of measurement.

- Magnetic Keepers. If two magnets are placed side by side there will be mutual repulsion or attraction. This weakens the strength of the magnet. To prevent this, bar magnets are placed side by side with opposite poles near. A soft iron piece called a keeper is placed across the poles as shown in figure.This soft iron piece provides a path for the magnetic field lines to form a continuous loop.Thus it helps in preserving the magnetic field.f two magnets are placed side by side there will be mutual repulsion or attraction. This weakens the strength of the magnet. To prevent this, bar magnets are placed side by side with opposite poles near.

- This is misleading, because Gauss does not increase by adding more magnets to a product. Gauss rating strictly depends on the chemical composition of a magnet. For example: If there are 10 magnets in a product, and each one is rated at 10,000 Gauss, the Gauss rating is still 10,000 (not 100,000). Another example: If the temperature in each corner of a room measures 70°F, the room temperature is 70°F (not 280°F). Back to the FAQ overview.

Austenite Austenite only forms when an iron-based alloy is heated above about 750°C (1382°F) but not above about 1450°C (2642°F). Austenite keeps its form at room temperature when special alloying elements have been added to the iron-based alloy.
