# What happens when the circuit for an inductor is suddenly open circuited?

A current through an inductor cannot change abruptly, so what happens if I have an inductor with current passing through, and I suddenly open circuit it so that no current flows through?

• You get an arc (hence the diodes protecting solenoids). – Jon Custer Oct 21 '16 at 17:16
• I believe the circuit technically explodes in this case. – Lelouch Oct 21 '16 at 19:05

$$v(t) = L\frac{di(t)}{dt}$$
