What is the direction of the induced current in the loop for each situation?

AI Thread Summary
The discussion focuses on determining the direction of induced current in a loop based on changing magnetic flux, utilizing Lenz's Law. Participants emphasize the importance of identifying whether the magnetic flux is entering or exiting the page for each situation before analyzing the changes. One contributor clarifies that in situation four, the magnetic field is directed into the page. The conversation suggests a systematic approach by labeling the examples to ensure clarity in communication. Understanding the initial magnetic field directions is crucial for accurately predicting the induced current's direction.

Clearly in situation 4, the field threading the loop is into the page - as signified by the crosses.

First step would be to establish the direction of the flux threading the loops in the other 4 examples. - ie into the page or out of the page.

Once you have established the direction of the flux to start with, we can analyse how that flux is changing; and thus the direction of the induced current.

SO get back with those initial B directions.

I see the examples as
1. top left
2. top right
3. lower left
4. lower centre
5 lower right

Just so we know we are referring to the same example each time.

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}...

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...
