This area is given by: >>center<< Area = half height times base = ½ (N Φ) I >><< Since L I = N Φ: Area = ½ (L I) x I Thus the energy stored in an inductor is proportional to the product of the inductance and the square of the current, i.e. E = ½ L I'^2^' where E is the energy (in Joules), L is the inductance (in Henries), and I is the current (in Amps).
