Are Spliced magnets better or whole magnets better?

If the magnet properties (including materials, shape, and magnetic properties) of a splicedmagnet are exactly the same as a solid magnet, then the solid magnet will generally have greater magnetic properties in the absence of other factors interfering with it.
To be part of a permanent magnetic motor, what are the magnets’ requirements?

Sintered Neodymium Iron Boron (NdFeB) magnets are very powerful magnets, often with high magnetic properties, but at the same time require special handling and design to meet the requirements of motor applications.
