Lesson: Self-Inductance of an Inductor
In this lesson, we will learn how to calculate a conducting loop's self-inductance from the change rates of emf induced in it and the magnetic field produced by the loop.

A coil with a self-inductance of 3.0 H carries a current that decreases at a uniform rate A/s. What is the emf induced in the coil?
What is the self-inductance per meter of a coaxial cable whose inner radius is 0.500 mm and whose outer radius is 4.00 mm?
An emf of 0.40 V is induced across a coil by changing the current through it. The current changes uniformly from 0.10 A to 0.60 A in 0.30 s. What is the self-inductance of the coil?
