Describe the effects of magnetic fields on moving charges. Use the right hand rule 1 to determine the velocity of a charge, the direction of the magnetic field, and the direction of the magnetic force on a moving charge. Calculate the magnetic force on a moving cha...
Shockley and James have noted that an electrically neutral magnet whose moment is changing with time exerts a force on an electric charge of negligible velocity at a large distance from it, but that there is no obvious corresponding back... S Coleman,JH Van Vleck - 《Physical Review》 被引...
We developed magnetic attractors capable of aggregating the cells remotely into a 3D embryoid body. This magnetic approach to embryoid body formation has no discernible impact on ESC differentiation pathways, as compared to the hanging drop method. It is also the base of the final magnetic device,...
Whereas self-propelled hard discs undergo motility-induced phase separation, self-propelled rods exhibit a variety of nonequilibrium phenomena, including clustering, collective motion, and spatio-temporal chaos. In this work, we present a theoretical fra
on the surface of carbon fibre, which, by enhanced electron transport in the conductive network (see Fig.8), improves electrical conductivity, dielectric polarisation, magnetic loss performance and interface interaction. As reported by Lu et al. [161], such composites attain resistivity up to two...
Using S. algae CECT 5071 as model organism, we were able to demonstrate quantitatively the influence that the culture medium exerts not only on the biofilm density or thickness, but more importantly, on the biofilm structure and on its nanomechanical and physicochemical properties. CLSM showed two...
Magnetic hyperthermia allows to remotely induce local heat using the magnetic energy losses of magnetic nanoparticles under an alternate magnetic field (AMF), thus drastically reducing the harmful side effects at the surrounding healthy tissues [104]. Importantly, a number of studies describe magnetic ...
(30) has a form of a grazing track of an outermost point of the sealing ring (32), so that during the movement of the sealing ring (32) on the annular seat (30) along the force of only on the inner side of the annular seat (30) along the sealing ring (32) on the annular ...
The perpendicular-to-film-plane magnetic field with induction B = μ0H populates the microstrip with a lattice of Abrikosov vortices. The applied dc current exerts a Lorentz force on the vortices that causes their motion with velocity v across the microstrip. The associated voltage drop V ...
25 Numerous experiments in real microgravity (on sounding rockets, satellites and the Space Shuttle) documented that the cells are definitively able to respond to gravity rather than with respect to the magnetic field of the Earth.26 The threshold for the gravity-induced response is found at ≤0...
