coils

DNA coils coiling into coils which again coil into coils...

I believe that damage to the lungs is a real possibility, especially if the voltage is too high in the coils.

Wibotic’s answer is to use tuned electrical circuits in place of simple transmitting and receiving coils.

A bunch of things that fail often are cheap ($100 - $200): starter battery, ignition coils.

There is still strong mutual coupling in the near field if the coils are mutually resonant.

In both the TV and light fixtures, you are hearing the transformer coils physically shifting.

There are patents for dynamic magnetic stripes that have individual coils for each bit.

It's obviously too late now, but you can actually get piezoelectric cartridges with no coils or magnets, made for (very) low-end phonographs.

But ultimately the way they've chosen to do this seems to be very difficult, especially if those are two very long single coils.

Why it looks like there's 2 coils is curious to me as well.

There are two hidden membrane switches to either side of the coils.

They're 'open' for that same reason, that way the magnetic field goes through the coils rather than that it heats up the steel and generates waste heat.

Be shellèd, eyes, with double dark And find the uncreated light: This ruck and reel which you remark Coils, keeps, and teases simple sight.
