The functions of ferrite magnets are as follows:
1. Isn't ferrite able to withstand high temperatures up to 450 degrees? The general ferrite can only reach 200 degrees.
2. Magnetic shielding or electromagnetic wave absorption.
3. It has an adsorption effect, but the adsorption force is very small, and one group is conductive, and it is more used in motors.
Ferrite magnets are divided into permanent ferrite, soft ferrite, and microwave ferrite. Permanent ferrite includes barium ferrite and strontium ferrite. Soft ferrite is divided into manganese-zinc ferrite, nickel-zinc ferrite, magnesium-zinc ferrite, and microwave ferrite includes yttrium ferrite. There are also hexagonal ferrite and so on. Ferrite magnets are hard and brittle, and require special machining processes. The heterosexual magnet is oriented along the manufacturing direction and must be magnetized in the direction taken, while the same magnet can be magnetized in any direction because it has no orientation, although a slightly stronger magnetic induction is often found on the side where the pressure is the smallest. The magnetic energy product ranges from 1.1MGOe to 4.0MGOe. Due to its low cost, ferrite magnets have a wide range of applications, from motors and speakers to toys and handicrafts, so they are currently the most widely used permanent magnet materials.
