What are Ceramic Magnets?
Ceramic magnets are also called ferrite magnets or craft magnets and have been a scientific subject of research since the 20th century. In the course of time, two types of ceramic magnets have been developed: soft and hard ferrites, which differ mainly in their composition. While soft ferrites have a low coercive field strength, that of hard ferrites is stronger. The higher the coercivity, the better the ability of a magnet to maintain its magnetization when exposed to an opposing magnetic field.
The main component of both types of ceramic magnets is iron oxide (Fe2O3). Strontium or barium ferrite make up the remainder of the magnet. Ferrite magnets are also axially magnetized, meaning that the north and south poles are on opposite sides of a horizontal line. In diametrically magnetized magnets, however, the north and south poles would be on opposite sides of a vertical straight line.
Visually, ferrite magnets can be identified by their black color and the fact that they are not coated with an alloy, unlike neodymium magnets. If you want to know what else distinguishes ceramic magnets from neodymium magnets, continue reading.
What is the difference between neodymium and ceramic magnets?
In addition to craft magnets, you can also order a wide range of neodymium magnets from GAUDER. Neodymium magnets have a very strong holding force at a small size and are used in many areas of industry and technology, for example in electrical appliances or lighting systems.
Neodymium magnets and ceramic magnets differ not only in their strength, but also in their temperature resistance. While ferrite magnets can withstand temperatures from -40 °C to 250 °C effortlessly, magnets made of neodymium react much more sensitively to heat and coldness.
Therefore, when buying the magnet of your choice, you should pay attention to where it will be used: On outdoor surfaces or in extremely hot places, you should opt for ferrite magnets so that you can enjoy your magnets for a longer time. If, on the other hand, you are primarily concerned with the adhesive force of a magnet, neodymium magnets are more likely to be the right choice. Regardless of whether they are made of ferrite or neodymium, you can pick your desired shape and size comfortably and flexibly in our GAUDER online shop.

What shapes of ceramic magnets are available at GAUDER?
In our online store, you can order craft magnets in three different shapes and designs:
- Round ferrite Disc Magnets are small and handy and therefore perfect for attaching postcards, drawings or photos to refrigerators. With these round magnets, you can design your kitchen according to your own ideas.
- Ceramic bar magnets have a rectangular shape. As with disc magnets, you can also use them to attach documents of any kind to magnetic surfaces. Or you can utilize them in your workshop at home, for example for tools or modeling.
- Ferrite ring magnets are also called ferrite ring cores or simply ferrite rings. Because of their circular shape, these practical magnets make it easy to turn decorative and craft projects from your imagination into reality. Try them out for yourself and take a look at our guide for inspiration.
Ferrite magnets from GAUDER are characterized above all by their first-class quality. They are processed to a high standard, can be used universally and are very robust. Therefore, you can be sure that you always make the right choice when choosing a GAUDER product, no matter which model.
What are ceramic magnets used for?
You encounter products with ferrite magnets in your everyday life more often than you might think. Ferrite magnets are used in various fields of technology, such as
- electrical engineering,
- high frequency technology,
- computer technology,
- audio technology,
- stealth technology or
- industrial technology.
But craft magnets are not only employed in technology. Ferrite magnets are also used as closures for bags or simply to attach photos, postcards or notes to magnetic surfaces. For example, your favorite refrigerator magnets from vacation are ceramic magnets.
You can also get creative yourself with craft magnets from GAUDER and develop your very own areas of application. For this, check our guide for inspiration.
Ceramic magnets as teaching aids for schools and universities — shop now at GAUDER
Ferrite magnets are ideal for attaching teaching materials to blackboards, whiteboards and other surfaces. This way, all important information is visible to everyone at all times and no important documents, such as worksheets or lesson plans, get lost.
You surely remember science lessons in school when you were first taught about magnets. With magnets made of ferrite, you can ideally demonstrate the magnetic field and the position of the poles yourself in physics or science lessons using exciting experiments. Both can be demonstrated with the help of iron powder. Let your students discover the magnetic effect of craft magnets on their own!
In the GAUDER online shop, you can order from a large selection of school magnets, depending on which shape or size you prefer.
GAUDER Ceramic Magnets — Your advantages at a glance
Ferrite magnets, also called ceramic magnets, are dark gray to black, non-coated and axially magnetized. They consist of ceramic-like material, a large proportion of iron oxide (Fe2O3) and a proportion of barium or strontium ferrite. They have no electrical conductivity. The composition determines whether they are hard magnetic, anisotropic (stronger) or soft magnetic, isotropic (weaker) ferrites. The softer the ferrites are, the lower the coercivity. We offer ferrite magnets in the shapes of disc magnets, square magnets and ring magnets.
Ceramic magnets are very resistant to heat and corrosion and have a high resistance to chemicals, which is why they are mostly used in industry. They can withstand temperatures from -40 °C to 250 °C, are rust-resistant and therefore ideal for outdoor use. GAUDER craft magnets can also be embedded in modeling clay in industry and 'baked' along in the process of machining.
Ferrite magnets are used primarily in industry and electrical engineering. Soft magnetic ferrites are used, for example, in ferrite antennas, to modify conduction properties, in high-frequency technology or to seal microwave devices. Hard magnetic ferrites are used as permanent magnets in permanently magnetically excited electric motors and loudspeakers, for pinning vacation souvenirs to the refrigerator or for closing bags.
