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 \(\rm\ V/m\).
