There's also "Why is a Coil not a Short Circuit? All this and more with a Little Theory and a lot of Practice". This is longer, but probably more instructive, also practical. It goes into coils.

You can go down the rabbit trail of inductors, the coiled wire. Electricity automatically causes magnetism. Magnets move electrons, which are (electrically) charged particles. But the flow of electricity changes over time for some reason. I don't know how that prevents a short circuit. I guess inductors are used for alternating current, not direct current.
 
 
 
 

2. If you wrapped the cord from your vacuum cleaner around a metal rod, wouldn't that be an electromagnet?

NEW No, it doesnt work because current is going both ways in the two cords, and the magnetic fields cancel each other out. Someone tried it here.
 
 
 

Gas ovens are ignited using the piezoelectric effect. What about lighters?

The piezoelectric effect is when you hit a crystal you get electricity. When you hear "click click" when turning on your gas stove, that is a little hammer hitting a crystal to make a spark. Some gas ovens anyway.

Your classic cigarette lighter uses friction with ferrocerium against steel, while some cigarette lighters use the piezoelectric effect. The bigger lighters used with barbecues are definitely piezoelectric.
 
 

I used to look forward to catching this on oldies radio. There is a variety of elements that come together to make this a nice song. But it's also a magic song because others have covered it, and each version has qualities. The version from Australian band The Executives / live, has been slowly growing on me, with its relaxed, meowing sound. It is similar to The Mojo Men. The song was written by Steven Stills. Here is the version from Buffalo Springfield. This is good, but (to my ears) is good in spots, with its relaxing introduction and especially the guitar climax in the middle. And then theres the hard-charging version from Growing Concern. For something entirely different, there is the version from The Staccatos. Love that acoustic guitar etc. introduction. Is this what they call baroque rock? Canadian band The Staccatos became The Five Man Electrical Band ("Sign. Sign. Everywhere a sign.").
 
 
 
 

I've gained a reputation as someone who is from another age, at least regarding music. Not someone who grew up in a different age; it predates that. I like '60s music.
(Some of those '60s tunes, good ones, actually date from the '30s. Winchester Cathedral, an odd but nice one, emulates the sound of the 1930s, a specific singer.)
I like a loong list of '60s tunes. In addition, there is a tiny but growing number of '60s films I like or am curious about.

But I dispute the assertion that I am someone from another age.
 
 
 
 
 
 
 
 

This reporter, a former Navy SEAL in Ukraine, describes the semi-successful attempts to take down the Kerch bridge linking Crimea with Russia. Ferries too.

It's interesting how much analysis must have gone into this. I wonder how that truck bomb worked. Suicide truck bomb? Did the driver not know, à la Spiderweb? This appears to be a very slick operation, timed to go off when the fuel train was passing. However, Mr. Pfarrer has mentioned multiple times that this was coincidence. I'm not sure why there are men with the unmanned autonomous vehicle.
