These square ferrite magnets, also known as ceramic magnets, are isotropic and therefore do not produce a magnetic field that is as strong as similar magnets that have an anisotropic alignment. Their isotropic characteristics mean that they can be magnetised in any direction. Ferrite magnets have a high resistance to corrosion and demagnetisation and their great advantage is that they can operate in temperatures of up to 180 degrees Celsius. These magnets are ideal for craft making, model making and other non-technical applications where a really strong magnet is not necessary
