Classical plasmas in thermodynamic equilibrium should be neither paranor diamagnetic due to the action of the Lorentz force. Magnetic confinement, however, is based on the observed diamagnetism of laboratory plasmas. The apparent paradox is investigated on the basis of the resistive magnetohydrodynamic equations. It is found that, at least in simple plasma configurations, these equations do not...

We analyze radiation reaction for synchrotron radiation by computing, via a multipole expansion, the near field and derive from it the Lorentz four-force, which we evaluate on the world-line of the charge. We find that the temporal component of the self four-force agrees with the radiated power, which one calculates in the radiation zone. This is the case for each mode in the multipole decompos...

Magnetoacoustic tomography with magnetic induction(MAT-MI) is a noninvasive technology for imaging the distribution of electrical impedance in biological tissue. In the sameple, a time-varying magnetic field induces currents. A static magnetic field interact with the currents to produce a Lorentz force. Consequently, the sample will emit ultrasonic waves by the Lorentz force. The objective of t...

Recently, a new technology for stably levitating and controlling the position and orientation of a rigid body has been introduced. A unique feature is the use of Lorentz forces rather than the usual Maxwell forces as in magnetic bearings. The Lorentz force approach, which uses the force experienced by a conductor in a magnetic eld, is seen to have several advantages. After an initial exploratio...

This study presents the first observation of elastic shear waves generated in soft solids using a dynamic electromagnetic field. The first and second experiments of this study showed that Lorentz force can induce a displacement in a soft phantom and that this displacement was detectable by an ultrasound scanner using speckle-tracking algorithms. For a 100 mT magnetic field and a 10 ms, 100 mA p...

Superconducting cavities are highly susceptible to small changes in resonance frequency due to their narrow bandwidth. At the proposed linac for the TESLA Linear Collider [1] the frequency changes resulting from mechanical deformations caused by Lorentz force detuning of the pulsed cavities will be of the order of the cavity bandwidth at the design operating gradient close to 25 MV/ m. The addi...
