    Loops Project
AI Thread Summary
The discussion focuses on designing an experiment to determine which factor most affects the strength of an electromagnet: the number of coils, voltage, core diameter, or wire thickness. The user seeks clarification on the concept of "loops," specifically in the context of feedback loops in the scientific method. They express confidence that the number of coils will have the most significant impact on electromagnet strength. The user is looking for guidance on creating two feedback loops to incorporate into their experiment. Understanding and implementing these loops will help refine their hypothesis based on experimental results.

Homework Statement


I need to get 2 major loops in my method or hypthesis. My experiment is which of the following factors affects strength of electromagnet the most: number of coils, the
voltage of the power source, the diameter of the core, or the thickness of the wire.

Can you guys give me loops that I can do with each of these factors. I'm in high school.


Homework Equations


None


The Attempt at a Solution


I really don't know. The loops is the only spot I'm stuck on.

What do you mean by loops? Flaws?
 
I mean a feedback loop. The feedback loop is in the need to go back to the "Asking a Question" stage should the experiment stage not support the answer stage (Hypothesis).
 
I believe that the number of coils will affect its strength the most. I haven't had anything go wrong yet so I would llike to know what feedback loops might I try because I need 2.

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}...
