Flexible magnets contain magnetic particles captive inside a flexible polymer binder. Flexible magnets are used for unique applications that would not be possible using other ‘hard’ magnets.
Did you know? The seal on every refrigerator door is made from a flexible magnet.
Generally, flexible magnets have a maximum energy product of 0.6MGOe to 1.6MGOe, this is poor compared to neodymium magnets at 42.0MGOe but whilst their magnetic power is small per cm2, when utilised over a large contact area, a considerable force can be generated, enough to securely hold magnetic signs to the side of a car or van at speeds up to 100mph!
There are two different categories of flexible magnets – magnetic sheet and extruded magnetic profiles.
