How Does Cooling Affect the Longevity and Strength of Neodymium Magnets?

[Hypo]

Hallo everyone!

As you all know one of the strongest rare-earth magnet is Neodymium.

I was wondering... under very cooled temperatures their magnetism will last for a longer time as usual and their magnetic field will be stronger than before too!
How long do you think it could last? I mean imagine if its magnetism's strength is rated at 100% how long will you think that number will last."Keep in mind that the magnet will constantly be introduced to a magnetic field will that effect its magnetic fields strength too?"

Thanks!
Can't wait for you answers!

Hello there!

I can confirm that Neodymium is indeed one of the strongest rare-earth magnets currently known. It has a high magnetic energy product, which is a measure of its ability to generate a strong magnetic field.

To answer your question, the strength of a Neodymium magnet's magnetic field will indeed be affected by temperature. Cooling the magnet can increase its magnetic field strength, but this increase is not permanent. As the temperature increases again, the magnet's magnetic field strength will decrease.

In terms of the duration of the magnet's magnetic field strength, it is difficult to give an exact time frame as it depends on various factors such as the initial strength of the magnet, the temperature at which it is cooled, and the rate at which it is introduced to a magnetic field. However, in general, the increase in magnetic field strength due to cooling will last for a few hours to a few days.

As for the effect of constantly introducing the magnet to a magnetic field, this can also impact its magnetic field strength. Over time, the constant exposure to a magnetic field can cause the magnet to lose some of its strength. Again, the exact time frame for this will vary depending on the strength of the magnet and the strength of the magnetic field it is exposed to.

I hope this answers your question. As always, it's important to remember that scientific experiments and observations are needed to accurately determine the effects of temperature and exposure to magnetic fields on the strength of a Neodymium magnet's magnetic field. Thank you for your question and interest in this topic!
