Long Cylindrical Solenoid#

A long, cylindrical solenoid with \({{ params.n }}\rm\ turns/cm\) has a radius of \({{ params.r }}\rm\ cm\).

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 \(\rm\ H/m\).

Part 2#

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

Answer Section#

Please enter in a numeric value in \(\rm\ V/m\).
