Magnetic field concentration using ferromagnetic material ...

Since the ferromagnetic material concentrates or increases only one side of the load coil wire's magnetic field intensity, a greater Lorentz force is generated in the magnetic material of that region, as shown in Fig. 4(a). The resulting imbalance in the Lorentz force thus generated can be utilized as the propulsive force for the micro-robot.

Mineral processing - Wikipedia

The force experienced in the magnetic field is given by the equation f=m/k.H.dh/dx. with k=magnetic susceptibility, H-magnetic field strength, and dh/dx being the magnetic field gradient. As seen in this equation, the separation can be driven in two ways, either through a gradient in a magnetic field or the strength of a magnetic field.

The objective of this work is to analyze the origin of the magnetic concentration gradient force. The force will be studied in a diffusion system where a paramagnetic electrolyte diffuses through a thin, inert membrane under the influence of a homogeneous magnetic field. The force will be analyzed using the theory of magnetic circuits, i.e., by the concept of minimum reluctance principles.
