|Near Field Attraction (Safety)|
Near field attachment is one of many features that polymagnets can be programmed to exhibit that improve safety in magnetic products. The near field feature gives you the ability to retain the magnets attach strength while reducing the effective distance of the field. Based on your requirements, the magnet can be designed specifically for use near magnetically sensitive materials and media. Even highly sensitive devices such as the internal compass of an iPhone can be very close to the magnet and remain fully functional.When attaching to a metal surface the near field functionality also allows for uninhibited alignment and positioning before attaching the magnet firmly in place.
|Reduced waste via field optimization|
When attaching a magnet to another magnet or to a metal surface, conventional magnetic fields follow a very basic form with a north pole on one side and a south on the other. This simple field shape rarely suits an attach configuration without a tremendous waste of potential energy. Polymagnets can be programmed for truly optimized magnetic field, essentially eliminating field waste helping the magnet demonstrate its full power.
|Size and weight flexibility|
Polymagnets can offer a 4x attach power increase compared to conventional magnets. Due to this increase of proficiency smaller and smaller magnets are being used where normally a fairly large magnet would be necessary. This reduction in bulk allows for aesthetic improvements while a reduction in weight will improve mechanical proficiency.
|Constraining Polymagnets based on function.|
Magnets will always find the easiest way to attach to each other. Sometimes in order for a poly magnet to function as intended, the magnet must be constrained to prevent it from shifting one way or the other to attach. The way that a polymagnet must be constrained is based on the function four which it is programmed. Most polymagnets need to be axially constrained to function properly. Make sure to check the description of the polymagnet(s) you are interested in to find out if it needs to be constrained.
|Surface area -vs- % increase of power|
Polymagnet technology can increase the attach strength of a magnet by up to 400%. The larger the surface area of the magnet the greater percentage increase you will see when comparing that polymagnet to a conventional magnet. Larger surface area = more power per $.
|Magnet thickness -vs- pattern resolution|
When the polymagnet machine magnetizes a spot or prints a "maxel", the top is fully saturated or completely magnetized. As the magnetization goes deeper it dissipates. If a magnet is too thick the "maxel" will not go deep enough to fully saturate the magnet and there will be wasted material behind the "maxel" or on the bottom of the magnet. To compensate for this phenomenon the maxel diameter must be increased so the maxel will reach deeper. This decreases the resolution of the polymagnet pattern due to the increased maxel size. Thicker the magnet the lower resolution of pattern and functionality.
|Distance or Gap vs Strength|
This is a universal rule for magnets though amplified in polymagnets. The distance between a magnet and the surface it is attaching to will dramatically affect the performance of the magnet. Direct contact will always be best for attaching magnet to magnet or magnet to metal. Polymagnets can be programmed to have the maximum attach force through a predefined distance. Conventional magnets will always be able to reach further than polymagnets.
|Metal Thickness -vs- Strength|
When attaching to metal, the thickness of the metal will affect the strength of the attachment.This is where polymagnets excel as they can be programmed to work with specific thicknesses of metal without wasting any of the magnetic field. For example, a conventional magnet will reach very deep into the metal and waste some magnetism that goes clear out the other side. With polymagnets the magnetic field can be concentrated in the range of the metal thickness.
|Steel Backing for extra power|
Steel backing increases safety and magnetic field strength by absorbing the field on one side of the magnet and reflecting it to the other side.
|Effectiveness over distance|
The effective range of a magnet is controlled by the distance between north and south poles. The field stretches from one pole to the other. On a conventional magnet the north and south pole are on opposite ends so the field must stretch out larger. On polymagnets the north and south are on the same face creating a short distance between poles and essentially keeping the field from stretching. In short, conventional magnets will always have a larger field and reach further than polymagnets.
The maximum print area of the polymagnet printer is (5 x 5in) or (127 x 127mm)
Currently the polymagnet printer can magnetize magnets no thicker than (0.5in) or (12.7mm)
