Programmable magnetizing realized by the Magnetic Printer can produce complicated magnetic patterns and is suitable for mass production and prototyping. The Polymagnet features many functions such as spring, latch, align, snap, torque, hold, twist, or release in smart magnetic devices.
Residual Induction (Br) and Coercivity (Hc) are usually the most important conditions to consider when selecting permanent magnet materials. Current technologies have allowed Foresee to produce some of the MGOe magnets with the highest M and H coercivity. How to strike a balance between the magnet's expected output and the risk of demagnetization is the key to material selection.
Revealing the Mystery of the Cases where Magnetic Like Poles Attract Each Other
In a pair of like poles, the magnet with higher Pc may causes local demagnetization (LD) to the other magnet with lower Pc. LD reduces the local field strength and even reverses the polarity of the local region, and the LD region can be attracted to the other magnet in a small gap resulting same poles attracting to each other.
