-Authors propose the spherical electromagnetic actuator that applied Surface Motor. The feature of this actuator is the ability to arrange the magnetic poles uniformly by distributing the stator's magnetic poles in triangular lattice. In this paper, we report that the fundamental structure of this actuator and secondary side permanent magnets arrangement, and we measure the thrust force charact...

It is verified that the Marinov motor works and that its torque magnitude roughly agrees with the theory given by Wesley (1). The existence of this device appears to refute the widely-held belief of physicists that the Lorentz force law suffices to describe all observable electromagnetic force manifestations.

We induce nanometer-scale surface deformation by exploiting momentum conservation of the interaction between laser light and dielectric liquids. The effect of radiation force at the air-liquid interface is quantitatively assessed for fluids with different density, viscosity and surface tension. The imparted pressure on the liquids by continuous or pulsed laser light excitation is fully describe...

We present an analysis of the behaviour of the electromagnetic self-force for charged particles in a conformally static spacetime, interpreting the results with the help of optical geometry. Some conditions for the vanishing of the local terms in the self-force are derived and discussed. PACS: 04.20.Cv, 04.70.-s, 04.90.+e

We have performed measurements of the Casimir force between a metallic plate and a transparent sphere coated with metallic films of different thicknesses. We have observed that, if the thickness of the coating is less than the skin-depth of the electromagnetic modes that mostly contribute to the interaction, the force is significantly smaller than that measured with a thick bulk-like film. Our ...

Microsensors and microactuators are considered to be the most crucial elements of micro-electromechanical systems (MEMS) and devices. There has been growing interest in the development of new microactuator technologies with an increasing requirement for low cost microswitch arrays providing large air gap and large force at the same time. In particular, large air gap/large force microactuators a...

Long time ago to calculate back-reaction of electromagnetic field on moving with acceleration a charged classical (not quantum) particle of finite size Sommerfeld [1] considered two models uniformly charged rigid sphere and uniformly charged rigid ball and found out explicit expressions for electromagnetic self-forces. These expressions in nonrelativistic limit are much simpler then the origina...

electromagnetic forming is a high energy rate forming process in which an electromagnetic lorentz body force is used for deformation of products.  in this article, electromagnetic forming process was simulated for the assembly of parts as an innovative method.  the effect of important process parameters such as discharge energy, radius and width of rectangular groove on the strength of the asse...
