12.7 Motional EMF In Chapter 10, the total force on a charge q moving with velocity v→ in a magnetic field B→ and an electric field E→ was shown to be (12.20)F→ = q(E→+v→ × B→), known as the Lorentz force. It was assumed that ...
Also, the motional emf due to the Lorentz force formula explains the direction of the induced emf. Is it conventional for the induced current to flow in the direction of increasing induced voltage (from negative to positive terminal)? Electric Machinery Fundamentals 5th E...
However, a high motional-electromotive force (EMF) is generated by rotor rotation in the single winding, which already has side-effects on the normal suspension force current, and the suspension force response can be delayed. Because the method of double torque current inverse injection in the ...
Another promising quantum platform with application in high-precision sensing is the system of laser-cooled trapped ions, which allows excellent control over the internal and motional degrees of freedom7. Force sensitiv- ity of order of 170 yN Hz−1/2 (10−24 N) was reported recently ...
