A magnetic ornament system includes: a mounting structure with a mounting surface; a magnetic plate, including a plate body, an adhesive material, and a protective member; and a magnetic ornament, including a magnet, a connector member, and an ornament assembly; such that the magnetic plate is positionable on the mounting surface of the mounting structure, such that the magnetic ornament is detachably connectable to the magnetic plate.

A sintered R.sub.2M.sub.17 magnet is provided that comprises at least 70 Vol % of a Sm.sub.2M.sub.17 phase, wherein R is at least one of the group consisting of Ce, La, Nd, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm,

Yt, Lu and Y, and M comprises Co, Fe, Cu and Zr. In an area of the R.sub.2M.sub.17 sintered magnet of 200 by 200 μm viewed in a Kerr micrograph, an areal proportion of demagnetised regions after application of an internal opposing field of 1200 kA/m is less than 5% or less than 2%.

A multi-functional magnetic bracket includes a first bracket with a magnet disposed therein to magnetically attach the first bracket to mobile phone; a second bracket movably connected to the first bracket through a connecting arm, the second bracket and a hinging arm being accommodated to inside of the first bracket, and a ring and a tooth slot opened in the second bracket; and a connector disposed in the second bracket and combined with the second bracket to form a multi-platform bracket for mounting the second bracket on different scenarios and platforms. The connector includes a base of which a surface is adhered to the platform, a limiting buckle disposed in the base and of which one end extends to a side of the second bracket, and a spring bead disposed in the base and of which one end extends to inside of the tooth slot.

A system and method control magnetic adhesion of a wheel to a surface using internal cancellation magnets. An inner annular disc of the wheel comprises a non-magnetic material and has first and second apertures which retain magnets while an outer annular disc comprises a ferromagnetic material and is disposed on a side of the inner annular disc and has a non-magnetic isolator ring which extends in a serpentine manner. In one configuration, the curves of the serpentine isolator ring isolate the first magnets from the second magnets. In another configuration, the outer annular disc rotates relative to the inner annular disc to dispose the curves of the serpentine isolator ring in a second position to allow magnetic interaction between the first and second magnets to generate a second magnetic flux between the second magnets and the ferromagnetic surface to thereby decrease the adhesion of the wheel to the ferromagnetic surface.

A process for magnetically sorting biological objects includes the steps of applying a magnetic field generated by a magnetic assembly to a flexible conduit; flowing a sample fluid containing magnetically labeled biological objects through the flexible conduit to collect the magnetically labeled biological objects on a conduit wall; removing the magnetic field from the flexible conduit; and mechanically deforming the flexible conduit to loosen the magnetically labeled biological objects collected on the conduit wall.

The present disclosure discloses a wearing member, a wearable device, and a charging system. The wearing member includes a housing and one or more electronic devices. The housing includes a first connection section and a concave section. The concave section is connected to one end of the first connection section, and the concave section forms a downward hollow in a wearing state. At least a portion of the one or more electronic devices are disposed in the concave section. Through the above manner, the wearing member disclosed in the present disclosure can utilize an installation space therein fully, optimizing a layout of the one or more electronic devices, which minimizes the wearing member and improves the utilization rate of the space.

An operation device that provides a clicking sensation, with a compact size and excellent durability. The operation device includes an operation member operated by a user. A magnet has a plurality of magnetic poles and is fixed to the operation member. A movable member includes a first magnetic pole portion and a second magnetic pole portion and is pivotally movably arranged on the magnet. When the operation member is operated in a state in which an attractive force is acting between a magnetic pole of the magnet and the first magnetic pole portion, the attractive force acting between them is reduced. Further, by the movement of the movable member, an attractive force comes to act between another magnetic pole of the magnet and the second magnetic pole portion.

A magnetic set-up for use in a rotary encoder is disclosed. The set-up includes a permanent magnet arrangement including at least one permanent magnet, which is rotatable with respect to a rotation axis, and a soft magnetic sleeve encompassing the rotation axis and thus the permanent magnet arrangement for shielding against external magnetic fields. The at least one permanent magnet includes a through-hole, which extends along the rotation axis, so that the permanent magnet fully extends around the rotation axis.

An electro-permanent magnet (EPM) for an electromagnetic mooring system (EMS) includes a low coercivity magnet surrounded by a reversible coil, and one or more high coercivity magnets surrounding the low coercivity magnet and the reversible coil. The reversible coil switches polarity of the low coercivity magnet to null the stronger, one or more high coercivity magnets. The nulling of the stronger, one or more high coercivity magnets allows for the EMS to connect and disconnect to an adjacent apparatus.

The present disclosure relates to a dual hybrid electromagnet module for controlling a microrobot. More specifically, the present disclosure relates to an electromagnetic field system in which a dual hybrid electromagnet module including a permanent magnet and an electromagnet is used for controlling a microrobot so that it is possible to reduce the number of used electromagnets so as to reduce power consumption and the amount of heat generated from the electromagnet module. The electromagnetic field system is capable of being used for various medical procedures and surgeries using a microrobot.
