Coils and Solenoids inducing Current and an electromagnetic paperclip gun

In this video I connect a coil to an ammeter to demonstrate induced current by a changing magnetic field. Then I connect another coil to 18 V, place it over the other coil, and demonstrate how the changing magnetic field produced by the changing current in one coil can induce current in separate circuit. I then repeat with solenoids. Then, for fun, I use 36 V and a solenoid to magnetically shoot a paper clip.
