Powerful Rare Earth Magnets
What are powerful rare earth magnets?
Powerful rare earth magnets are also known as neodymium magnets, they are the strongest rare earth magnets around. Neodymium magnets are graded by the strength that they can be magnetised to.
What are the powerful rare earth magnets’ grades?
Powerful rare earth magnets are graded from low to high strength. The grades are as follows: N35, N40, N42, N48, N50, and N52.
Are powerful rare earth magnets dangerous?
Powerful rare earth magnets are not dangerous on their own, however, should you swallow two magnets, or you swallow a magnet with another metal object the strong magnets can attract each other and can cause significant internal damage.
What makes these magnets so strong?
Powerful rare earth magnets are so strong because of the high resistance they have to demagnetisation, they have high levels of magnetic saturation, which allows them to generate large magnetic fields.
How long do these magnets last?
Powerful rare earth magnets are known as permanent magnets, this means they only lose a tiny fraction of the magnet’s strength every 100 years (if they are well looked after and maintain good working conditions).
Are there any magnets stronger than the neodymium one?
Iron Nitride is more powerful than a neodymium magnet, compared to rare earth magnets the costs are very low.
Where are rare earth magnets used?
Powerful rare earth magnets are used in many day-to-day appliances such as speakers/headphones, wind turbines, computers, fishing reels, cordless tools, and various motors.
How much do they cost?
Powerful rare earth magnets can start at as little as a couple of pounds, obviously depending on how many you buy and the grade you go for.
