Energy stored in inductor (1/2 Li^2) | Electromagnetic induction | Physics | Khan Academy
An inductor carrying current is analogous to a mass having velocity. So, just like a moving mass has kinetic energy = 1/2 mv^2, a coil carrying current stores energy in its magnetic field giving by 1/2 Li^2. Let's derive the expression for it using the concept of self-induction. Khan Academy is a nonprofit organization with the mission of ...
