A magnetic apparatus (1) comprising a magnetizable surface (2) configured to anchor a one or more ferromagnetic elements in a removable manner and a plurality of magnetic poles (3), each provided with a free surface (4) thereof, the magnetizable surface (2) being at least partially defined by the free surfaces (4) of said plurality of magnetic poles (3) placed side by side; one part of said magnetic poles (3) has at least two measuring areas (5) on the free surface thereof, each measuring area (5) being associated with at least one sensor (6) adapted to detect a magnetic flux exiting from said area.

A tool for selectively engaging and disengaging one or more magnetic connectors to secure a panel. The tool includes a frame with one or more magnets. The magnets provide a magnetic flux to control the magnetic connectors. In use, the tool is positioned on a first side of the panel with the one or more connectors on the opposing second side. The magnetic flux from the one or more magnets controls the positioning of the connectors between engaged and disengaged positions.

A periodic arrangement of magnets are used to form structures that channel the potential energy that a magnet possesses into kinetic energy in a controlled fashion to perform some useful work or function. One function is to create a magnetic chute that converts the potential energy of a magnetic projectile into kinetic energy that is used to channel the projectile to follow a path achieving high velocities along a path. The path is formed by assembling magnets periodically along the path in a certain fashion to create a magnetic chute that allows the magnetic projectile to slide easily along the path since the projectile is confined by the shape of the magnetic chute.

The present invention relates to a holding magnetizer, which can: maintain a strong magnetic force even if away from the tip of a driver bit, regardless of the length of the bit, when mounted on the bit so as to perform screw work; reduce or remove magnetic force when the magnetic force needs to be weakened in accordance with work circumstances; use a screw holding ability so as to prevent a screw from being separated from the bit and being lost; and remove iron powder, generated by screw abrasion during work, when the iron power is attached to the tip of the driver bit.

The invention relates to an apparatus (100) and a method for the processing of magnetic particles (MP) provided in a processing chamber (114) with a binding region (116) to which said magnetic particles (MP) can (specifically) bind. Removal of unbound magnetic particles (MP) from the binding region (116) is achieved by first separating them from the binding region (116) by gravitational forces and then moving them further away by magnetic forces. Gravitational forces can for example be generated by tilting the binding region with a tilting unit (156). The prior separation by gravitational forces prevents that unbound magnetic particles (MP) are captured in a cluster with bound magnetic particles.

An electromagnetic lifter for moving hot materials is disclosed. The lifter has a ferromagnetic yoke formed by a horizontal core and two vertical polarities, lifting coils wound around the core and enclosed in a container, a non-magnetic baffle arranged between the vertical polarities and below the container at a distance of at least 40 mm to protect it from the heat radiated by the hot material to be moved, as well as side spacers and top spacers which keep the container away from the polarities and the core respectively.

A holding tool to handle a first permanent magnet in a stack of permanent magnets is provided. The holding tool comprises a body including a holding portion including an electromagnet, and a switch disposed on the body and electrically connected to an electrical circuit of the electromagnet and configured to energize the electromagnet by connecting the electrical circuit and de-energize the electromagnet by disconnecting the electrical circuit. The holding portion includes a hollow member made of ferromagnetic material and a coil surrounding the hollow member to form the electromagnet and the electromagnet is configured to, when energized in a first current direction, have a polarity opposite to a polarity of the permanent magnets in the stack.

This relates to a holding apparatus for holding a component during mounting. The holding apparatus comprises at least a first holding unit including at least one magnetic field generating device for generating a magnetic field, and at least a second magnetic holding unit spaced apart from the first holding unit in a predetermined distance for receiving the component. A holding force for holding the component between the first holding unit and the second holding unit is generated in the second magnetic holding unit as a result of induction and by means of a magnetic field generated by the magnetic field generating device. The embodiment also comprises a mounting system and a method for holding components by means of such holding apparatuses.

An apparatus and method for unloading a rotor bearing is described. The apparatus includes an electromagnet for levitating the rotor. In one embodiment, a sensor of the magnetic field near the electromagnet is used to control the current to levitate the rotor. In another embodiment, a method is provided that includes rotating the rotor, increasing the current to levitate the rotor and decrease the gap between electromagnet and rotor, and then reducing the current to levitate the rotor with a minimal amount of electric power to the electromagnet.

Additive manufacturing systems are disclosed. The systems may include a build platform, and at least one magnet positioned adjacent the build platform. The magnet(s) may be configured to manipulate a magnetic powder material positioned on the build platform to form a pre-sintered component having a first geometry. The system may also include at least one sprayer nozzle positioned adjacent the build platform, where the at least one sprayer nozzle may be configured to coat the pre-sintered component formed from the magnetic powder material with a binder material. Additionally, the system may include at least one radiant energy component positioned adjacent the build platform. The radiant energy component(s) may be configured to sinter the pre-sintered component to form a sintered component having a second geometry identical to the first geometry of the pre-sintered component.
