Ceramic Ferrite Magnet Pull Force

Ceramic ferrite, also known as hard magnetic ferrite, is one of the widely used permanent magnet magnets, typically characterized by cheap, high temperature and corrosion resistance, today's article focuses on the pull of this magnet.


How much less pulling force does a ceramic ferrite magnet have than a neodymium magnet?

Ferrite magnets are not as strong as rare-earth neodymium magnets, and similarly sized magnets usually provide only about 1/7th of the pulling force.


Y30 grade block ferrite magnets, Magnetization can be selected in length, width or thickness direction.

Y30 grade block ferrite magnet


Below are some pull strength data for common specifications of ceramic ferrite magnets:

Block ferrite magnet 25x10x6mm, Y30BH tensile strength about 0.8kg


Square length magnetized ferrite magnet 10x10x5mm, Y30 grade tensile about 0.09kg


Rectangular length magnetized ferrite, Y30BH grade pull about 0.22kg


Ring ferrite 20x5x8mm, Y30BH grade vertical pull about 0.62kg


Ring ceramic magnet 32x18x5.5mm, each anisotropic Y30BH grade pull about 1kg


75 x 50 x 20mm ferrite magnet block, vertical pull approx. 5kg


100x50x12mm Y30BH ferrite ring, Y30BH grade vertical pull about 8.8kg


100x75x6mm rectangular ferrite, Y30BH grade vertical pull approx. 4.5kg


From the above data we can see that the performance is not excellent, the same specifications of neodymium magnets, the pull force is much larger, the specific pull force and magnet size, shape, grade (Y35 magnetic properties and pull force is slightly higher than Y30), surface contact conditions and so on.


Is there a formula for calculating the pull force of ferrite magnets?

There is no simple general formula and some calculations are inaccurate. To obtain an accurate pull force value, you need to refer to the test data provided by the magnet supplier.
