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) ]

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
