# EMF/Eddy Currents Induced in a Hollow Cylindrical Conductor

I'm attempting to figure out the total current induced in a hollow metal tube as a result of the EMF due to a constantly varying magnetic flux through its cross-section.

Faraday's law of induction states that for an infinitely thin loop of wire in such varying magnetic flux has induced EMF $ε=-\frac{d\phi}{dt}$.

For a cylindrical solenoid composed of N circular windings of wire, the EMF induced is $ε=-N\frac{d\phi}{dt}$.

My question is: How would one go about calculating the EMF induced in a continuous metal tube? Or, if possible by any other means, the how would one find total current induced around the tube?
