The relationship between B and H can be described as equation (1): H = B/µ-M (1). where H is magnetic field strength (A/m), B is magnetic flux density (T), µ is magnetic permeability, and M is magnetization. To describe the distinguished biological effects, the fields are gra...
The equation for the magnetic force on a particle in a magnetic separator depends on the magnetic susceptibility of the particle and fluid medium, the applied magnetic field and the magnetic field gradient. This equation, when considered in only the x-direction, may be expressed as (Oberteuffer...

As the magnetic field increasing, the equation of state becomes stiffer. 可以看到随着磁场的增加状态方程变硬. 来自期刊摘选 9. When current flows through a coil, a magnetic field will be built up round the coil. 当直流电流过线圈, 就会在线圈的周围产生磁场. 来自期刊摘选 10. The results show ...
The amount of charge which flows through any conductor per unit time is known as current and we can express it by $I = \dfrac{q}{t} = \dfrac{{2e}}{t}$ Substituting the values in above equation, We will get, $I = \dfrac{{3.2 \times {{10}^{ - 19}}}{2} = 1.6 \times {...

Two types of magnet-related forces can cause injury in a patient with a bio-implant: (a) an attractive transitional force that is proportional to B0, gradient field strength, and the mass, shape and magnetic susceptibility of the object, and (b) the torque that attempts to align or rotate...
But the charge per unit time is the current, q/t = I, so we have I=nev and the force on the wire becomes (12-4)FM=BIL (v⊥B) Equation 12-4 is correct if the direction of the wire is perpendicular to the field direction. In the event ...
