Long Cylindrical Solenoid#

A long, cylindrical solenoid with $params.n\mathrm{t}\mathrm{u}\mathrm{r}\mathrm{n}\mathrm{s}/\mathrm{c}\mathrm{m}$ has a radius of $params.r\mathrm{c}\mathrm{m}$.

Part 1#

Neglecting end effects, what is the self-inductance per unit length of the solenoid?

Answer Section#

Please enter in a numeric value in $\mathrm{H}/\mathrm{m}$.

Part 2#

If the current through the solenoid changes at a rate of $params.dIdt\mathrm{A}/\mathrm{s}$, what is the emf induced per unit length?

Answer Section#

Please enter in a numeric value in $\mathrm{V}/\mathrm{m}$.
