An electrical composite assembly includes a plurality of composite material macro-wires each including a magnetic material embedded within a nonmagnetic matrix. The magnetic material can be selected from magnetic microwires, magnetic nanowires, chains of magnetic nanoparticles, and chains of magnetic ...
Magnetic fields with large spatial gradients impose a sufficient force on magnetic particles (paramagnetic or diamagnetic) and are even capable of altering cell functions [14,15,16]. The magnetic properties of many biological species are weak, although they can be enhanced by proper contrast [17,...
to line up in the direction of the field. Magnetic fieldsforcemoving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation ofelectric motors. (For more information about magnetic fields,see...

A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron. The force (F) is equal to the charge (q) times the speed of the particle times ...
As magnetophoretic forces move the particles, they also experience an opposing drag force 𝐹𝑑Fd. For spherical particles in laminar flow, the drag force (opposing the magnetophoresis) relates to the radial particle velocity 𝑣𝑟𝑎𝑑𝑖𝑎𝑙vradial by Stokes’ law, 𝐹𝑑=6𝜋...
Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged particles. A magnetic field exerts a force on particles known as the Lorentz force, according to Georgia State University's HyperPhysics website. The ...
The horizontal component of this pulling force was created by the magnetic field gradient at the trailing edge of the magnet and had to overcome the static friction keeping the microchips in place. The intensity of static friction depends on the coefficient of friction between the microchips and ...
Based on this effect, 2D colloidal particles lattice was assembled on Ni grid with different morphologies in paramagnetic Ho(NO3)3 solution22. Simple 3D structures, for example, the spheroidal tissue-like models, have also been obtained via magnetic levitation devices in a more biocompatible ...
MFL starts with a magnet. A magnet has two ends, called north and south poles. The poles exert forces on iron and steel. This force of attraction is caused by the magnetic field.Figure 7.2illustrates the flux lines around a magnet and its poles as calculated using finite-element analyses....
