Mutual inductance of two coaxial solenoids | Electromagnetic induction | Physics | Khan Academy

Let's calculate the mutual inductance of two coaxial long solenoids.

Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

thanks a lot, we want also videos about capacitor

Assuming the two coils were identical in length, wire diameter and number of turns than, the mutual inductance is proportional to the cross section area only?
For the same current.

Just a little doubt sir .. when calculating M12 .. won't the magnetic field be "UoNI/L2 rather than /L1 .. so this condition would only satisfy actually for an infinite solenoid .. in which case we take the magnetic field to be UoNI without adding L1 or L2 into it ?
