Magnetic strength can be multiplied by up to 32 times by using
steel armatures to concentrate magnetic flux. Such armatures may
take the form of backing plates, channels or cups. The maximum
increase in power is obtained when magnets are sandwiched between
two plates. Add a hook or knob, and these magnets are perfect for
holding and positioning shop lights, tools, plants and more to
steel surfaces such as refrigerators, filing cabinets, metal beams,
walls and doors.
Features: 1) Made of iron, steel with sintered ferrite, sintered NdFeB and
cast alnico gluing together. 2) Sintered NdFeB pot magnets and cast alnico pot magnets maintain
their magnetic properties under extreme heat conditions, and are
ideal for industrial requirements. 3) For daily life use as holding magnets.
