Lorentz-force hydrophone characterization
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2014 A Lorentz-force hydrophone consists of a thin wire placed inside a magnetic field. When under the influence of an ultrasound pulse, the wire vibrates and an electrical signal is induced by the Lorentz force that is proportional to the pulse amplitude.

Ultrasonically-induced Lorentz force tomography [PDF]
Medical & Biological Engineering & Computing, 2009 Electrical conductivity can be measured using the ultrasonically-induced Lorentz force. An ultrasonic wave is passed through tissue in the presence of a magnetic field. Moving charges in a magnetic field are subject to the Lorentz force, which acts as the source of current and potential.

Is There a Dynamic Difference between Stealthy and Standard Coronal Mass Ejections?
The Astrophysical Journal, 2022 Stealthy coronal mass ejections (CMEs), lacking low coronal signatures, may result in significant geomagnetic storms. However, the mechanism of stealthy CMEs is still highly debated.

The Casimir Force in a Lorentz Violating Theory [PDF]
, 2006 We study the effects of the minimal extension of the standard model including Lorentz violation on the Casimir force between two parallel conducting plates in vacuum. We provide explicit solutions for the electromagnetic field using scalar field analogy,
