As always, look to the bottom of the post for background on what's going on. Finally, enough of theory and presentations! I got back to the lab today! Here’s the apparatus I built/used. NOTE: As always, look to the bottom of the post for background on what's going on. No, the oscilloscope is not sticking its tongue out, that’s a floppy disc. Remember those? The small solenoid is what’s deemed a pickup coil. It’s the first prototype, of the coil that will be used to measure the actual currents and magnetic fields produced by the can crusher magnet. It’s exactly what it looks like, six complete turns made from a jumper wire. The Styrofoam cup is to avoid abusing the small magnet block too much when it’s dropped. The ‘scope pictured can capture a single waveform. Here, it’s slowed way down to make a sweep over the course of several seconds. It’s being used to look at the...
