    In 1997, the first near room-temperature proof of concept magnetic refrigerator was demonstrated by Karl A. Gschneidner, Jr. by the Iowa State University at Ames Laboratory. This event attracted interest from scientists and companies worldwide who started developing new kinds of room temperature materials and magnetic refrigerator designs. [7]

    These so-called ceramic magnets are cheap, and are widely used in household products such as refrigerator magnets. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30–160 kiloampere turns per meter (400–2000 oersteds). [33] The density of ferrite magnets is about 5 g/cm 3.

    Maybe all flexible fridge magnets use the narrow stripe (Halbach array) arrangement of poles (on one face) (all mine do, 4 or 5 mm repeat)), but many solid fridge magnets use circular hard magnets - some of these have alternating poles on the face, and some don't. Many with discs 15 mm diameter (4 mm thick) have a single N or S pole on each face.
