Calculating Magnetic Field of Solenoid Coil with AC Current

AI Thread Summary
To calculate the magnetic field of a solenoid coil with AC current, the process differs from that of DC current. The inductance (L) can be measured using an RLC meter at the operating frequency. The equation H = NI/L is applicable for AC current, but it requires using the RMS value of the current (I). The discussion emphasizes the importance of understanding the relationship between inductance and the magnetic field in AC scenarios. Proper application of these principles is essential for accurate calculations.

Hello
I want to calculate field of the Solenoid Coil with AC current.
For a DC current field is calculated easily from the BiotSavart.
What is the process for AC current?
Get the L value with RLCMeter in operating frequency?
Is there an equation to get the field with inductance?(H=\frac{NI}{L})?
The equation is true for AC current?
Should I put the RMS value in the equation? [ or i=I sin(ωt) ]

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}...
