where B=(Bx,By,Bz) is the magnetic flux density. This integration is automatically done in the Comsol framework. As both the rotor and stator are axi-symmetric, there is no angular dependence on the force. This also means that the force on the rotor will be the same regardless of the ...
Understanding Magnetic Flux Density: Before we dive into the specifics of our Magnetic Flux Density Converter tool, let's briefly discuss the concept of magnetic flux density. Magnetic flux density, often referred to as B, is a measure of the strength and direction of a magnetic field. It is...
34. The results with finite magnetic field predict that the amplification becomes threefold (≈8.94/2.62) under B = 10 T and temperature 316 nK. The analytical formula in Eq. (3), and the parameter values can be found in “Experimental designs”. Full size image Results Free ...
Magnetic flux density B (or magnetic induction) The magnetic flux density B at a point is a vector quantity arising from the magnetic field and the magnetisation of the medium. It is given by: B=μ0H+μ0M or B=μ0H+J where µ0 is the magnetic constant. The units of B are tesla...

This predicts that the critical current density is determined by the balance between this torque and the pinning torque. The rotational motion of flux lines driven by to the restoring torque that exceeds the pinning torque explains the observed break in Josephson’s formula on the induced electric...
Preferably, the soft magnetic ribbon is represented by the composition formula Fe 100-x-y Cu x X y (wherein X is at least one element selected from among B, Si, S, C, P, Al, Ge, Ga and Be), in which the atomic percents (%) satisfy the relationships 0<x≦5 and 10≦y≦24....
