A refrigerator magnet or fridge magnet is a small magnet, often attached to an artistic or whimsical ornament, which may be used to post items such as shopping lists, Christmas cards, child art or reminders on a refrigerator door, or which simply serves as decoration.

3. Halbach array - Wikipedia

   en.wikipedia.org/wiki/Halbach_array

   Magnetic viewing film showing a flat refrigerator magnet's magnetization Flat flexible (not hard ceramic ferrite ) refrigerator magnets are created with a Halbach magnetization pattern for a stronger holding force when attached to a flat ferromagnetic surface (e.g. a fridge door) than the holding force from a uniform magnetization.

4. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   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.

Science projects : Many topic questions are based on magnets, including the repulsion of current-carrying wires, the effect of temperature, and motors involving magnets.

6. Ferromagnetism - Wikipedia

   en.wikipedia.org/wiki/Ferromagnetism

   An example of a permanent magnet formed from a ferromagnetic material is a refrigerator magnet. [ 2 ] Substances respond weakly to three other types of magnetism— paramagnetism , diamagnetism , and antiferromagnetism —but the forces are usually so weak that they can be detected only by lab instruments.
