Do you know what a ferrite magnet is and what are its benefits? Well, ferrite magnets are found in their simplest form as they consist of iron oxide mixed with barium carbonate or strontium carbonate. These components are heated above 1000 degree Celsius temperature in the absence of air. After that, they are cooled and milled to a fine powder which is further compacted into a die and sintered at high temperature. And the resultant magnet is extremely hard and strong. However, magnets made from ferrite have a maximum flux density of 4,000 gauss approximately. There are many companies which manufacture ferrite magnet block and can be easily affordable.

Points to Consider When Buying Ferrite Magnet Block
Due to its low cost, ferrite magnets have huge applications. However, some facts are there which is to be considered when you are going to buy ferrite magnets. They are stated below:
1. Whether the ferrite magnet is soft or hard, it does not affect the hardness of the material.
2. A soft magnet has a low coercivity that’s why it is useful for alternating current applications such as high-frequency transformers and switched power supplies.
3. Hard ferrite magnets possess high magnetic permeability and a strong residual magnetic field, hence it is used in loudspeakers, DC motors, and so forth.
4. Ferrites are sintered so they can be molded into different shapes like blocks, discs, and rings.
5. They are not suitable at temperatures below zero, they may permanently lose their magnetism.
6. They do not require corrosion protection for outdoor use because they have corrosion- resistant property.
7. They are easy to handle because of their lower magnetic flux density.
Thus, these are the reasons why many companies buy ferrite magnets instead of expensive ones.
