SUMMARY

The discussion focuses on calculating the magnetic flux through a toroidal inductor with a given inductance of 4.50 mH and 125 coils carrying a current of 11.5 A. The correct formula for magnetic flux (φ) is derived from the relationship φ = L * I, where L is inductance and I is current. The final calculation yields a magnetic flux of 0.05175 Wb for the entire inductor, and approximately 4.14 * 10^-4 Wb per coil after dividing by the number of coils.

Homework Statement



A 4.50 mH toroidal inductor has 125 identical equally spaced coils.

4.5 mH = .0045 H (Wb/A)
N = 125
I = 11.5 A
φ = ? - this is what we're finding

If it carries an 11.5 A current, how much magnetic flux passes through each of its coils?

Homework Equations


I'm really blank on this one. I know that the units for the magnetic flux, φ, will be in units Wb. My educated guess is that the equation will be φ = inductance/current.

The Attempt at a Solution



φ = (.0045 H)/(11.5 A) = 3.91*10^-4 Wb
I divided that by 125 and got 3.13*10^-6 Wb

Ah shi. How dumb of me. Just after posting I realized that I should multiply the inductance by the current and got the correct answer.
 
nvm, got it.
