What are the disadvantages of ferrite magnets?
Ferrite Magnet
1. Poor magnetic force. This is the biggest shortcoming of ferrite. The reason for not choosing it is largely because the magnetism is not up to the requirement.
2. Large size. Weak magnetism naturally requires a larger volume. Many high-tech products such as smart phones and robots use neodymium iron boron with small size and strong magnetism.
3. The tolerance control is not precise. The tolerance of ferrite magnets is usually larger than that of neodymium iron boron. Of course, ferrite can also be finished. The magnetic ring can be internally ground and externally ground, but the cost is relatively large.
4. It is not easy to be processed into special-shaped and complex magnet shapes. This is also the main reason why most of the ferrite magnets we see are discs and squares.
Oh, it turns out that ferrite magnets still have so many shortcomings, do you know all of them?
