Magnetic field of a conventional magnet (left) and two polymignite
Polymagnet American company for several years produces magnets with arbitrary shape of magnetized material polymignite. They are fundamentally different from conventional magnets and have different properties that are set before printing. For example, these magnets can be automatically aligned relative to each other or to keep a predetermined distance from each other (in millimeters), starting with the reduction of this distance (similar to latches) or, on the contrary, bonding in excess of the distance, but not touching each other (similar to spring), demonstration, see under the cut.
Importantly, you set arbitrary properties in the program editor, and then for a few minutes to print your own magnet. The properties of the magnet are selected from a catalogue of pre-programmed polymignite or set arbitrarily.
Polymignite about 5 times stronger than ordinary magnets because they have the energy of the field is concentrated near the surface. The North and South poles in an arbitrary number can be on one side of polymignite.

The magnet spring can be programmed, for example, that the magnets approach each other, but not touching, until one of them rotated by 180º. After locking the magnets it is difficult to tear away from each other, if not rotate one of them 180º. This construction can be used, for example, in magnetic locks.

Magnetized layer is applied to metal using a powerful magnetizing coils special printer like MagPrinter. It is somewhat reminiscent of a 3D printer that not only prints with plastic or metal, and magnetic field. But here, too, the arbitrary form is set by computer editor.

You can imagine different use cases of polymignite: locks and latches in doors and furniture, precisely positioned prior joining together gadgets and other electronics, magnetic couplings, fasteners for road transport and bicycles, mounting shelves and other furniture items together (instead of screws), a variety of toys, designers, and more.
