A vehicle comprises a chassis supported by wheels for moveably carrying the chassis in a driving direction, a steering wheel for turning a steering column around a rotation axis, and a steering angle sensor for measuring a rotation angle of the steering column with an encoder that is stationary to the steering column and with a magnet sensor that is disposed axially displaced from the encoder on the rotation axis. The encoder includes a first magnet with a top side directed to the magnet sensor and a second magnet attached to the first magnet opposite to the top side. The first magnet includes a recess starting from the top side, and each magnet is magnetized orthogonal to the rotation axis. The first magnet and the second magnet are displaced against each other in rotation direction. The recess has a depth lower than an axial thickness of the first magnet.

A magnetization device includes an outer casing, a base, a rotatable hood, an object-carrying seat, and a drive mechanism. The rotatable hood includes a receiving space. The rotatable hood has a circumferential wall that includes a pair of magnets mounted thereto, with one N pole and one S pole of the magnets being pointing toward the receiving space of the rotatable hood to induce magnetic lines of force and a magnetic field therebetween. The object-carrying seat is disposed in the receiving space of the rotatable hood to support a magnetized object. The drive mechanism drives the rotatable hood to rotate around and outside the magnetized object, such that the magnetized object is kept stationary and the magnets, and thus the magnetic lines of force and the magnetic field, are driven by the rotatable hood to rotate around the magnetized object.

An input device comprising a processor(s), an input element, an electropermanent magnet (EPM) assembly including: a permanent magnet operable to generate a magnetic field; and a magnetizing assembly configured to set a magnetic field generated by the permanent magnet, a first ferromagnetic element, and a second ferromagnetic element. The first ferromagnetic element is configured to part and move away from the second ferromagnetic element as the input element is depressed. When the EPM assembly magnetizes the permanent magnet to a first polarity, the first and second ferromagnetic elements are magnetically attracted to each other and provide an attracting that magnetically opposes the first and second ferromagnetic elements from parting, and when the EPM assembly magnetizes the permanent magnet to a second polarity, the first and second ferromagnetic elements are not magnetically attracted to each other and do not magnetically oppose the first and second ferromagnetic elements from parting.

Processes for applying magnetic fields to articles such as a layer or layer-coated articles, and more particularly to coatings having graphite particles, preferably for manufacture of negative electrodes having aligned graphite particles, for example for fast-charging lithium-ion batteries. The application of magnetic fields may be continuous. For this, magnetic tools with permanent magnets may be used for applying magnetic fields, wherein an article is moved relative to a magnetic tool. Application of magnetic field is made before the initiation of a drying phase and/or during a drying phase.
