Flux and current equation
WebAs you notice from Eq. (1.18), the equation of continuity has two variables, the neutron density, n, and neutron current, J, as ϕ = nv where v is the average neutron speed in V. Thus, to solve this equation, one of the variables needs to be eliminated by combining Fick's law approximation and the equation of continuity. WebAug 4, 2011 · -- Assuming the circuit to be complete, I get a current flowing through the coil whose value is current = flux linkage / coil inductance As the magnet moves away from the center, the flux linkage decreases. However the magnitude of flux linkage is positive -- From the previous equation, current is still positive since flux linkage is positive
