In 10 years the magnet kt will only depolarise 1%. So that means it is going to take 1000 years to depolarise completely in temperatures below 180 F° I belive
Soft iron is not used for making permanent magnets; instead, it is used as a temporary magnet due to its high magnetic permeability and ability to be easily magnetized/demagnetized. Permanent magnets are typically made from hard magnetic materials like neodymium or ferrite, which can retain their magnetism for a long time.
Yes, as long as their spins are aligned, they will attract other materials whose spins are aligned, be they temporary or permanent.
The magnetic field would propagate through the material and extend itself for the length of the magnetic material in contact. As long as there is contact there is no pole present. When contact is broken the pole would be the opposite to the pole it was in contact with
What is little known, is that the whole of the UK is a giant magnet. This is why poles are attracted to it!
Weight and size do not affect an object's attraction to a magnet. The key factor is the object's composition - specifically the presence of magnetic materials like iron, nickel, or cobalt. Texture also does not play a significant role; as long as the material is magnetic, it will be attracted to a magnet.
Neodymium magnets typically last for several decades before losing their magnetic properties.
A neodymium magnet is known for its strong magnetism that can last for a long time. These magnets are made of rare earth elements and are commonly used in various applications where a strong, long-lasting magnetic field is required.
Neodymium magnets are known for retaining their magnetism for a long time due to their strong magnetic properties. They are commonly used in various applications where long-term magnetism is important, such as in electric motors and generators.
A temporary magnet can be magnetized or demagnetized easily, while a permanent magnet retains its magnetization over a long period of time. Temporary magnets are usually made of soft magnetic materials like iron, while permanent magnets are made of hard magnetic materials like neodymium or ferrite. Temporary magnets require an external magnetic field to maintain their magnetism, whereas permanent magnets do not.
A temporary magnet is something that has been magnetized that won't stay a magnet for long, such as a paperclip that you have rubbed with a magnet. A Permanent magnet is usually a Lodestone that is found naturally or is manufactured by a company. Permanent magnets are always magnetic.

By N52 your reffering to neodymium rare earth permenant magnets. This is not the only type of rare earth but no others reach this strength. The rare earth doesnt pass the N52 rating, but..the magnets "pull" strength or potential is inversly relates to its size, so a 1" diameter x 3" long n52 (magnetized through length) will pick up more then a say 1" cube. The influential magnetic field and pull increases as the size increases. You still have temperature to factor in as well, over 120degrees neodymium mags quickly lose strength. Ceramic is closer to 150 and at a point the strongest ceramic will be stronger then the strongest neodymium. If you need more juice step intothe world of electromagnets.
Some examples of permanent magnets are neodymium magnets, samarium-cobalt magnets, and alnico magnets. These magnets are made from materials that retain their magnetic properties for long periods without needing an external magnetic field to remain magnetized.
Neodymium magnets can last for many years, even decades, if properly cared for. Factors that can affect their lifespan include exposure to high temperatures, physical damage, and exposure to corrosive environments.
Iron, nickel, and cobalt are the most commonly used metals for creating permanent magnets. They have strong magnetic properties and can retain their magnetism over a long period of time. Other metals like neodymium and samarium can also be used to create powerful permanent magnets.
Screw SCIENCE!!
No, but if you leave the magnet in lemon juice long enough it will start to corrode.
