Homework Statement
An inductor has the form of a coil with 2074 turns and a diameter of 1.9 mm . The inductor is placed in a magnetic field perpendicular to the plane of the coil and increasing at a rate of 0.48 T/s . The current in the inductor is zero at t = 0, and then increases to 6.9 mA at t = 1.0 s. What is the inductance?
Homework Equations
This is the problem, I am obviously missing something.
I want to use the equation L= (u*N^2*A)/length.. but as you can see I am not given the length. I do not know how to incorporate the charge into finding the inductance.
The Attempt at a Solution
I feel like I am close. I am trying to use the increase rate of the magnetic field to find the emf, and then use the emf and the current to find the inductance, but then i get stuck.
