How Strong Are Ferrite & Ceramic Magnets?
You might already be aware that ferrite and ceramic magnets, a type of permanent magnet, have the capability to exhibit very high levels of strength. However, most people cannot say that they know exactly how strong one of these magnets are.
Ferrite & Ceramic Magnets Average Strength:
- 0.35 Tesla
- 30-160 Kiloampere
- 400 to 2000 oersteds
The strength of ferrite or ceramic magnet, in particular, is measured in a unit called Tesla. Teslas account for one weber per square meter within a magnetic field, which is equal to 10,000 gausses.
The average strength of a ferrite magnet is around 0.35 Tesla, with the strongest and most powerful medical MRI machine coming in at just 3 teslas, to give you a better idea of where these magnets stand.
The magnets’ strength is also measured bt the turns per meter that they are able to produce in terms of their magnetic fields. On average, a ferrite magnet will exhibit around 30 turns per meter, with the highest being 160.
Turns per minute is referred to scientifically as a kiloampere. The average statistics of 30 to 160 kiloampere translate to anywhere from 400 to 2000 oersteds.
Just one oersted is the equivalent to just under 80 amperes per meter, which is a relatively high number when it comes to magnetism.
Although these new terms of measurement might seem like a foreign language no matter how well they are explained, the next section will go over how ferrite magnets can be compared to other types of magnets that you might have heard of before.
Ferrite & Ceramic Magnets - Strength Comparison
Along with learning about the strength levels and capabilities of ferrite and ceramic magnets, it is helpful to be able to observe a direct comparison between these types of magnets and other categories.
Whether you have any previous knowledge of magnetism and the strength of some of the most basic types of magnets or if you are looking to learn about these topics, the list down below will give you a general explanation of where ferrite and ceramic magnets fall on the spectrum of strength.
How The Strength Of Ferrite & Ceramic Magnets Compares To Others:
- Stronger than metallic magnets
- Weaker than neodymium magnets
Due to the high level of magnetic permeability that ferrite and ceramic magnets possess naturally, they are able to give off stronger magnetic fields than most types of metallic magnets.
To be more specific, permeability is defined as the influence that a substance has on the magnetic fields that are existent in that specific area. So, ferrite and ceramic magnets are significantly stronger than magnets in the metallic category.
On the contrary, ferrite magnets are much weaker than neodymium magnets. This is because neodymium is one of the strongest magnetic materials in existence.
Neodymium magnets can be used within households as well as in industrial and commercial settings, with various different sizes and purposes. Most commonly found in the form of a disc magnet, neodymium magnets are widely used around the world on a daily basis.
To give you a better idea of how strong ferrite and ceramic magnets really are when they are up against their counterparts, they are stronger than metallic magnets but weaker than neodymium magnets, which puts them somewhere in the middle.
What Are Ferrite & Ceramic Magnets?
Ferrite magnets, also known as ceramic magnets, are a type of magnet that is made out of a mixture of metals that is called ferrite.

Ferrite Magnet Gauss
Ferrite magnet: Its main raw materials include BaFe12O19 and SrFe12O19. Manufactured by ceramic technology, the texture of ferrite magnet is relatively hard and it is a brittle material. Due to the good temperature resistance, low price and moderate performance of ferrite magnet, ferrite magnet has become the most widely used permanent magnet.
Ferrite magnet is a sintered permanent magnet material composed of barium and strontium ferrite. In addition to strong anti-demagnetization performance, this kind of magnetic material also has the advantage of low cost. Ferrite magnets are hard and brittle, and require special machining processes. The opposite 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.
Ferrite magnet is divided into permanent ferrite magnet, soft ferrite magnet, and microwave ferrite magnet. Permanent ferrite magnet includes barium ferrite magnet and strontium ferrite magnet. Soft ferrite magnet 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.
What is the role of ferrite magnet?
1. Magnetic shielding or electromagnetic wave absorption.
2. Isn't ferrite able to withstand high temperatures up to 450 degrees? The general ferrite magnet can only reach 200 degrees.
