what is the strongest rare earth magnetic material?
The magnitude of the magnet magnetic capability could decide to improve on the craft rises.otherwise it might shoot up at an intense volume of volatile velocity. you are able to desire to nonetheless have the craft have engines that activate as quickly as a undeniable elevation is reached that the magnet rigidity could be ineffective, probably the momentum could be of super information. additionally, earths magnetic poles are shifting and that they are not completely understood merely yet, so this is a confusing call to make if it could have any adverse effects on electronics or the magnet.
Rare-earth magnets are strong permanent magnets made from alloys of rare earth elements. Developed in the 1970s and 80s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field typically produced by rare-earth magnets can be in excess of 1.4 teslas, whereas ferrite or ceramic magnets typically exhibit fields of 0.5 to 1 tesla. There are two types: neodymium magnets and samarium-cobalt magnets. Rare earth magnets are extremely brittle and also vulnerable to corrosion, so they are usually plated or coated to protect them from breaking and chipping. The term rare earth can be misleading as these metals are not particularly rare or precious;[1][2] they are about as abundant as tin or lead.[3] The development of rare earth magnets began around 1966, when K. J. Strnat and G. Hoffer of the US Air Force Materials Laboratory discovered that an alloy of yttrium and cobalt, YCo5, had by far the largest magnetic anisotropy constant of any material then known
