Suppose we have a toroidal solenoid with square cross section and whose axis of symmetry lies along the z axis. Suppose a current I(t)=kt runs through the solenoid. Find the induced electric field at an arbitrary point on the z axis.

2. Relevant equations

[tex] \oint \vec E \cdot d \vec l = \frac{d \Phi}{dt} [/tex]

3. The attempt at a solution

I am wanting to use faradays law in integral form, but there doesn't seem to be a good path to integrate around such that the E field will be constant on the path. I have already found the B field generated by a steady current I. Is it applicable to use faradays law just replacing I in the formula for the B field with I(t)?

Any suggestions about how to start this problem correctly would be much appreciated!

Thanks,

Eric
