The history of ferrite magnets is more intriguing than you may realise. Here at MagDev, we decided to take a look..
It is quite possible that the history of magnets may have eluded you and that is quite understandable.
However, after doing some research, we found out the history is really quite fascinating, with the earliest reference to magnets dating back 2500 years.
Way back, the Greeks discovered magnetic Iodestones and started to use them in their early form.
The word magnetic actually derives from the Greek word ‘Magnetis Lithos’ which now translates to ‘Magnesian Stone’ in relation to where the stones were originally reportedly found somewhere in modern-day Turkey.
Since those ancient times, magnets have of course come into more common use but it was not until 1600 that the first scientific study of magnetism was published. William Gilbert was the man behind the publication ‘De Magenete’ which changed the face of magnets in the mass population’s eyes.
Closer still to the present day, in 1930, the first Ferrite magnet was produced rather accidently by Japanese professors Dr Yogoro Kato and Dr Takeshi Takei.
They produced what was known as ceramic magnet and, from the 1950’s, mass production of ferrite magnets began as alternatives to metallic magnets which are now commonly used in electronics.
So, what actually are Ferrite Magnets?
Ferrite magnets are a type of permanent magnet made of the chemical compound ferrite. This consists of ceramic materials as well as iron oxide.
The raw materials used to produce ferrite magnets are strontium, barium or strontium carbonate, and iron oxide, and their low production costs and resistance to heat and corrosion has made them popular for everyday applications.
It has been a long road for ferrite magnets but, after 2500 years, they have become a critical component of everyday life in multiple countries around the world.
