Can Induced EMF Be Greater Than Actual EMF and Create Opposing Currents?

AI Thread Summary
Induced electromotive force (emf) can indeed exceed the actual emf under certain conditions, particularly when the rate of change of magnetic flux (d(phi)/dt) is greater than the existing flux (phi). This scenario raises the possibility of induced currents opposing the original current that generates the magnetic field. The discussion also explores whether induced emf can create currents that flow in the opposite direction to the original current, emphasizing the distinction between induced currents and the magnetic fields they create. Overall, the relationship between induced and actual emf is complex and depends on the dynamics of the magnetic flux. Understanding these principles is crucial for applications in electromagnetism and electrical engineering.

If the induced emf = -d(phi)/dt that is the rate at which the flux through a body is increasing, can the induced current ever be more than the actual current so as to oppose the field created?
Because the rate at which the flux through a body is increasing can be greater than the flux it already holds (what i mean to say is d(phi)/dt > phi). So is it possible that the induced emf be more than the actual emf creating the current?

Also, do Induced emf actually create current flowing in the opposite direction of the current that is causing the magnetic field? (Not the the induced magnetic field)
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
