Generally, since most neodymium magnets are strong, they can last entire lifetimes, but jarring things like dropping it, hitting it with (say) a hammer, forcing opposite poles together, and extreme temperature changes can affect its duration.
The weight of a neodymium magnet can vary widely based on its size and strength. Common neodymium magnets used for everyday applications can weigh anywhere from a few grams to several kilograms.
If lightning struck a magnet, the magnet would not be affected much. Magnets are made of materials like iron or neodymium that are not easily damaged by heat. The lightning would likely dissipate through the metal without causing significant changes to the magnet's magnetic properties.
If a magnet is frozen too much, it can lose its magnetism temporarily. This is due to the rearrangement of molecules inside the magnet, disrupting its magnetic field. Once the magnet warms up to room temperature, its magnetism may return.
over time it will lose its magnetism. It will also lose its magnetism if it is temperature is to high or when it's vibrate too much.
A magnet Will pick up rust flakes And a magnet can get rusty looking however I don't think you can get much magnetism out of a piece of rust.
Per se - it doesn't. The reason to use a supercooled magnet is that the power consumption is much lower, so its a question of economics - not magnetism.
It will lose its magnetic properties.Indeed you are right...but in addition, during the process of intense increase in temperature, the magnet starts to lose its magnetism thereafter it utterly loses it magnetism, but starts to to regain its magnetism back as it cools. I recently discovered this after two trials with my stove. I propose that magnets may utterly lose their magnetism when exposed to temperatures beyond 800 degree Fahrenheit subsequently after the metal liquefies. victor onyegbulam
if a magnet gets dipped is salt it loses some magnetism this can be experimented if you put iron filings in a plastic cup filled with water, you will see the water loses its magnetic field and wont see much movement at all.
The production of a rare earth magnet, such as neodymium, consumes a significant amount of energy due to the need for high-temperature processing techniques. However, the exact amount of energy used can vary depending on the specific manufacturing process employed by the producer.
The simple answer is, it becomes weaker and weaker and eventually looses its magnetism. In a permanent magnet magnetic domains within the material are nearly all oriented in the same direction, amplifying the magnetic effect. As one heats this material, the domains become more random. When heated sufficiently high, to the CURIE POINT, the material loses all of its magnetism. If the material is then cooled in the presence of a magnetic field, it will be re-magnetized. In some materials, heating to temperatures below the curie point will result in temporary loss of magnetism which will be regained as the material cools (reversible losses). Heating to temperatures below the curie point may also cause irreversible losses, ie, the magnetism does not return to its previous strength when cooled.
the domain strength is much stronger in a magnetised nail. when you have a weak nail, there is no magnetic force. sometimes they can repell. this is what i think and i always know best thank you
A magnet will adversely effect the beams path by deflecting it once it passes close enough to the magnet. This is why magnets are used in the column of an eb weld machine. If a magnet were to be placed in an eb weld chamber and an the beam was shot at the magnet, the beam would deflect drastically. That said, I have personally welded parts containing magnets directly beneath the surface to be welded by using steel shunts to absorb the magnets pull. Although it didn't completley stop the magnets effect on the beam, it dampened the effect drastically and allowed for successful welding.
