magnetic field n. A condition found in the region around a magnet or an electric current, characterized by the existence of a detectable magnetic force at every point in the region and by the existence of magnetic poles. American Heritage® Dictionary of the English Language, Fifth Edition. ...
Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other. From this point of ...
Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to lin
Figure 2. When a charged particle moves along a magnetic field line into a region where the field becomes stronger, the particle experiences a force that reduces the component of velocity parallel to the field. This force slows the motion along the field line and here ...

(General Physics) a measure of the strength of a magnetic field at a given point, expressed by the force per unit length on a conductor carrying unit current at that point. Symbol:B Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 199...
electrolyte near the electrodes, and the resulting magnetic field gradient exerts a force on the fluid, which leads to a deflection of the Lorentz force-driven main flow. Particle Image Velocity measurements and numerical simulations demonstrate that by combining the two magnetic forces, the flow is...
Their potential also relies on unique features, such as magnetic responsiveness, ability to generate heat, localized magnetic field, improve magnetic resonance (MR) signals, and perform as energy transfer mediators or mechanical force vectors [86]. Generally, these smart nanocarriers are comprised by ...
