Oscillation Frequency for Peak Voltage

Click For Summary
SUMMARY

The discussion focuses on calculating the oscillation frequency for peak voltage in a loop of wire using the equation E(max) = NABw = 2πNABf. The key variable, N, represents the number of turns in the wire loop, which is determined to be 1 based on the problem statement. The user struggles with isolating N due to its absence in the provided data. The solution involves recognizing that for a single loop, N equals 1, simplifying the calculation of frequency to f = 1.50 / (2.50/100)^2 * π * 0.109 / (2π).

PREREQUISITES
  • Understanding of electromagnetism principles

Homework Statement



Here is the prompt:

Homework Equations



E(max) = NABw = 2pi*NABf

The Attempt at a Solution



E(max) = NABw = 2pi*NABf
= NA*B(nought)*2pi*f
1.50 / (NA*B(nought)*2pi) = f
f = 1.50 / N / ((2.50/100)^2*pi) / 0.109 / (2pi)

The problem I'm having is I don't know how to figure out N because it is not given, and I don't know any other equations that exclude the N variable.
 
Physics news on Phys.org
I suspect they have told you what N is.
What does N stand for in that equation?
 
N is the number of turns, and I suppose since this isn't a solenoid that N=1
 
That's the one - the problem statement specifically says "A loop of wire..." - that would be 1.

You could also have got there by applying the Laws of electromagnetism instead of trying to memorize specific results. Then you'd just derive an equation that never has an N in it... you'd feel more confident about the result too, but it would take a lot longer ;)
