Ferrite (Ceramic) Today’s refrigerator magnet – ceramic magnets with Barium or Strontium Ferrite – is the most common of all magnets. It is considerably inexpensive but it contains a lower strength compared to the other magnets. Developed in the 1960s, it was the “useful” magnet, used everywhere.
· There are typically four categories of permanent magnets: neodymium iron boron (NdFeB), samarium cobalt (SmCo), alnico, and ceramic or ferrite magnets. Neodymium Iron Boron (NdFeB) This type of magnet is composed of rare earth magnetic material, and has a high coercive force. They have an extremely high energy product range, up to 50 MGOe.

Magnetic nanomaterials have been given special attention by the scientists due to their countless applications in the recent era of science. However, highly magnetic storage devices, sensors, ferrofluids, magnetic resonance imaging (MRI), transformers, refrigeration system, and several other technological pillars are highly dependent on these materials [1,2,3,4].
How the refrigerator door remains closed? the weak ferromagnetic ceramics like barium ferrite or strontium ferrite present in the fridge magnet aligns the spins of unpaired electrons in metal atoms in the fridge in such a way that the magnet and the fridge door are attracted to each other; this force keeping the doors closed. (vi). Computer
· Ceramic magnets, like the ones used in refrigerator magnets and elementary-school science experiments, contain iron oxide in a ceramic composite.Most ceramic magnets, sometimes known as ferric magnets, aren’t particularly strong.; Alnico magnets are made from aluminum, nickel and cobalt. They’re stronger than ceramic magnets, but not as strong as the ones that incorporate a class …
A strong magnetic force is a great way to separate various metallic elements from one another. 2. Create a Magnetic Structure. A great and simple activity to do with magnets is seeing how their force will defy gravity. This is seriously so much fun.
