Why is the EMF induced, per the formula E = BLV, calculated with L as the length of the wire frame, instead of the length of the rod? Don't charges throughout the rod (including in the parts beyond the wire frame) move due to a Lorentz Force qvB, so EMF = work...
In summary, the conversation is discussing the calculation of the emf induced in a tightly wound coil at the center of a solenoid with specific dimensions and a varying current. The formula for calculating the magnetic field of the solenoid is mentioned, as well as the use of the solenoid's...
Relative motion between armature and rails in the railgun produces induced emf's. The Lorentz force formula correctly predicts the emf present in the armature but it fails to acknowledge the induction of further emf's in the rails which are proportional to the relative velocity. It is easy to...
Following the formula: power density=pulsedensity=pulse repetition frequency ×× single pulse microwave power/surface area of antenna, the power density in Ref. 55 is found to be 3.2W/m2, which is much smaller than the safe limit 10W/m2. It is worth noting that most well-studied MTAI ...

This theory has revealed important physics for RWM stabilisation by flow such as collisional effects and bounce and precession resonance effects4,5. From the experimental side, in the JT-60 tokamak device, it was observed that change of flow shear at the q = 2 surface affects the ...
