is there any material is more stronger than neodymium magnets?
I know that a lot of magnets are have the strong magnetic strengh, but i donn’t know is there any magnetic materail is stronger than the neodymium magnets?
and i found a website, it provide some kinds of magnet: http:www.china-magnet.net, and i found a ball magnet on this website, can u tell me how to recgnize it’s N or S?
Neodymium magnets are the strongest type of permanent magnet, with a field strength up to 1.4 Tesla.
Next best are Samarium-Cobalt, with a strength up to about 1.1 Tesla.
If you need a stronger field, you need to use an electromagnet, or even a superconducting electromagnet, which can reach much higher strength.
As for ball magnets, they are usually magnetized axially, with the two poles 180 degrees apart.
If they are not marked, the only way to know which pole is which is to test it with another magnet
with a known pole.
