A magnetic field exerts a force on particles known as the Lorentz force, according to Georgia State University'sHyperPhysics website. The force acting on an electrically charged particle in a magnetic field depends on the magnitude of the charge, the velocity of the particle, and the strength ...
The levitation forces under different field cooling states were measured at 77K by changing the field cooling distance Zfc between a YBCO bulk and a permanent magnet. It is found that the relationship between the absolute maximum attractive force (Final) and the corresponding gap distance (Zmaf) ...
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 ...
However, when dealing with the magnetic field inside materials, particularly ferromagnetic materials that concentrate the lines of force, the value of the induced flux density will be much higher than the field intensity. This relationship is used in high-gradient magnetic separation (discussed further...
The load F was generated by applying a spatially uniform magnetic field gradient to a superparamagnetic bead attached to the (+) end of the microtubule. When F was scaled by the average number of motors 〈 n 〉, the force–velocity relationship for multiple motors was similar to the force–...
In the magnetic case, however, the force FM is not in the direction of the field vector B, nor is it in the direction of the velocity vector v: FM is perpendicular to both B and v. We can see the relationship among these three vectors in the following simple experiment. Suppose that...
The Lorentz force deflection imposed on them thus induces a lower dose of protons in the zones of strong magnetic fields, and a concentration of the protons at the edge of the magnetic field zone. This is what is observed in the films, both exhibiting experimental and synthetic whiter zones ...
The structure is manifested through flare ribbons, intense optical and EUV emissions in footpoints of field lines attached to the coronal reconnection region. In the most common type of solar flares, two parallel ribbons appear and move away from each other, which could be related to the ...
distributed lines of force (magnetic flux). Magnetic lines of force are the invisible lines of force that make up a magnetic field. See Figure 2. The magnetic field surrounding a magnet has a greater density at the poles and radiates out into the space surrounding the magnet in a ...
