What is the strongest magnet? Do permanent magnets produce radiation?
China Rare Earth Magnet Limited customs permanent magnets including neodymium magnets, i.e. NdFeB, samarium cobalt magnets, i.e. SmCo, AlNiCo magnets & Ferrite / Ceramic Magnets
What is the strongest permanent magnet?
Currently, rare earth magnets have the highest performance, and neodymium magnets are the strongest. But, under temperature higher than 200ºC, samarium cobalt magnets are the strongest. Magnets can be classified into two kinds---one is soft and the other is hard. Soft magnets cover silicon steel sheets and soft magnetic iron cores, while hard magnets include AlNiCo, SmCo, ferrite and NdFeB magnets, samarium cobalt magnets are the most expensive, ferrite magnet is the cheapest one, neodymium iron boron is the highest-performance one and alnico magnet is the most stable one. Customers can choose different hard permanent magnets according to their requirements.
Reveal mysterious veil of magnetic performance
There are many metal ions, such as iron ions inside magnets. Due to unique electric structure, these ions with magnetism can be seen as small magnets with invariant strength. Under different temperature, these small magnets distribute in different direction, so their magnetism will be also be different. In high temperature, internal atoms of the magnets will vibrate fiercely and the small magnets will point to different directions. Under such circumstance, small magnets deflect toward the direction of external magnetic field, which shows up as weak magnetized strength belonging to paramagnetic behavior, which needs several Tesla (millions times as that of the earth) to gather all the small magnets at the same direction.
Do permanent magnets produce radiation?
Magnets produces magnetic field that can penetrate people and objects around them, and you can call that radiation. Magnetic field of common magnets does no harm to human. Even if there are such things as magnets, you still expose to radiation for the earth has magnetic field itself. Some people may feel uncomfortable when they are in a place without any magnetic field. At least, magnetic field is necessary for some animals. The scientific answer is that magnets have radiation but no radiation injury. Every object with temperature produced electro magnetic radiation, which is called blackbody radiation. It is inevitable that any natural materials contain radioactive material or radioactive rays. But radioactive strength in normal permanent magnets is not able to harm human body. If magnets move, it may produce electro magnetic radiation for it moves in magnetic field. However, this is can entirely be neglected unless its speed is very fast which is close to light speed.
