Opening switches in highly inductive circuits can be dangerous, even with low-voltage power sources. To see why, consider a 9 V battery supplying 3.0 A to an electromagnet with inductance 2.6 H. A switch in this circuit opens and the current drops to zero in a mere 6.7 ms.

What's the emf induced in the electromagnet during this time?
