Why outlets spark when unplugging - EMF & Inductors

I love the video and how excited you are while explaining all the physics. Ignore the killjoys... unless they're dead inside almost everyone would still be excited to see some physics at work no matter what level of physics knowledge they have or what level of difficulty the experiment/demo is. Keep up the good work!

Also, love this cos it's a good reminder of why it's not wise to pull a plug while the current still running or when sometimes you see sparks going off when you turn off a switch. Cos even if I know the reasonings, one tends to forget at times.
