Accordingly, the voltage control of magnetic anisotropy can be used to realize physical reservoir computing by spintronics devices without driving current or magnetic field. Here, we perform numerical simulation of the Landau-Lifshitz-Gilbert (LLG) equation and find that the computational capabilities of...
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 ...
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...
You will also learn about the solenoid magnetic field equation. What is a solenoid? If we run a current through a wire, there is a magnetic field around it. A solenoid is a wire wound tightly in a long, thin coil. Due to its shape, if we run current through the solenoid, there ...
The MHD effect is reflected in an additional term of Lorentz force in the momentum equation at each time step. In the present model, the MHD Lorentz force caused by the induced current is derived from the Ampere’s law by solving the induced magnetic field equations. Results based on the ...
Given a specific temperature T, the associated lattice vibration is tied with the probability that the direction of the magnetic domain can be flipped from parallel to antiparallel and vice versa. We define the mean time t between the two flips according to the Neel-Arrhenius equation11: $$t=...
This force has been used in laboratories for simultaneous levitation and melting of specimens with the heat generated due to the eddy currents in it [19]. A similar eddy current force is also generated when a conductor moves over a permanent magnet. This force restricts the motion of the ...
