A Novel 2-DOF Lorentz Force Actuator for the Modular Magnetic Suspension Platform. [PDF]

Sensors (Basel), 2020
The modular magnetic suspension platform depends on multi degree of freedom of Lorentz force actuators for large bearing capacity, high precision positioning and structure miniaturization.

Lorentz force induced shear waves for magnetic resonance elastography applications. [PDF]

Sci Rep, 2021
Quantitative mechanical properties of biological tissues can be mapped using the shear wave elastography technique. This technology has demonstrated a great potential in various organs but shows a limit due to wave attenuation in biological tissues.

Highly sensitive low field Lorentz-force MEMS magnetometer. [PDF]

Sci Rep, 2021
We present a highly sensitive Lorentz-force magnetic micro-sensor capable of measuring low field values. The magnetometer consists of a silicon micro-beam sandwiched between two electrodes to electrostatically induce in-plane vibration and to detect the ...

Lorentz Force Actuated Tunable-Focus Liquid Lens. [PDF]

Micromachines (Basel), 2019
Tunable-focus liquid lenses provide focal length tuning for optical systems, e.g., cameras, where physical movement of rigid lenses are not an option or not preferable.

Lorentz Force Velocimetry [PDF]

Physical Review Letters, 2006
We describe a noncontact technique for velocity measurement in electrically conducting fluids. The technique, which we term Lorentz force velocimetry (LFV), is based on exposing the fluid to a magnetic field and measuring the drag force acting upon the magnetic field lines.

The ponderomotive Lorentz force [PDF]

Nonlinearity, 2020
Abstract This paper describes a curious phenomenon: a particle in a rapidly varying potential is subject to an effective magnetic-like force. This force is in addition to the well-known ponderomotive force, but it has not been shown to exist before except for the linear case of a rapidly rotating quadratic saddle potential.

The role of non-axisymmetry of magnetic flux rope in constraining solar eruptions

Nature Communications, 2021
The competition between different components of the Lorentz force defines whether a solar eruption fails or not. Here, the authors show a new Lorentz force component, which plays a major role in preventing magnetic flux ropes from erupting successfully.

Winding vibration caused by Lorentz force in shunt reactor and its control strategy. [PDF]

Sci Rep
In each vibration source of shunt reactor, the winding vibration caused by Lorentz force should not be ignored. In this paper, the electromagnetic-mechanical coupling field simulation model was established based on the structure of disks and blocks of ...
