Largest possible size and power of a permanent magnet?
Largest possible size and power of a permanent magnet?
(OP)
The largest neodymium magnets I have seen have been no larger than 3"x6"x3". I'm wondering if there is a maximum physical size barrier in the magnetization process of the metals? Would it be possible to have a NdFeB magnet that is 1'^3?





RE: Largest possible size and power of a permanent magnet?
Aside from that, there is no theoretical limit to the size of NdFeB that can be magnetized. There are many practical limitations, such as safety (handling issues), coil size, cooling concerns, available energy from capacitors, etc.
The only practical way to manufacture a 1 cubic foot magnet is to assemble from smaller blocks. With the appropriate fixturing and adhesive, this is a fairly straightforward process.
