For cost-effective starter motor applications, the use of curved or segmented ferrite permanent magnets is a good choice. Ferrite magnets offer some of the following advantages.
Low price
Compared to NdFeB or other rare-earth permanent magnets, ferrite magnets are much cheaper in terms of raw material price, which helps to reduce the overall cost of the machine.
Moderate performance
Although the magnetic properties are not as good as rare-earth magnets, the performance of ferrite magnets can meet the requirements of starter motors and other applications that do not require high magnetic field strength.
High Temperature Stability
Ferrite magnets have a small temperature coefficient of coercivity and stable magnetic properties over a wide temperature range, making them suitable for hot environments such as engine compartments.
Strong corrosion resistance
Ferrite material itself has excellent corrosion resistance, without the need for complex protective measures, which is conducive to cost reduction.
Mature production process
Ferrite magnets have been in large-scale industrial production for many years, the production process is mature, and is conducive to the realization of automated mass production.

The magnets used in hard disk drives are very strong neodymium (rare earth) magnets. Typically a magnet will have a north pole on one face, and a south pole on the other face. Hard drive magnets differ in that they act like two magnets stuck together side by side. On one face there is a north pole on the left and a south pole on the right, on the other face there is a south pole on the left and a north pole on the right....
