A coil is a series of loops. A coiled coil is a structure in which the coil itself is in turn also looping.
An electromagnetic coil (or simply a "coil") is formed when a conductor (usually an insulated solid copper wire) is wound around a core or form to create an inductor or electromagnet. One loop of wire is usually referred to as a turn, and a coil consists of one or more turns. For use in an electronic circuit, electrical connection terminals called taps are often connected to a coil. Coils are often coated with varnish or wrapped with insulating tape to provide additional insulation and secure them in place. A completed coil assembly with taps is often called a winding. A transformer is an electromagnetic device that has a primary winding and a secondary winding that transfers energy from one electrical circuit to another by inductive coupling without moving parts. The term tickler coil usually refers to a feedback coil, which is often the third coil placed in relation to a primary coil and secondary coil. A coil tap is a wiring feature found on some electrical transformers, inductors and coil pickups, all of which are sets of wire coils. The coil tap(s) are points in a wire coil where a conductive patch has been exposed (usually on a loop of wire that extends out of the main coil body). As self induction is larger for larger coil diameter the current in a thick wire tries to flow on the inside. The ideal use of copper is achieved by foils. Sometimes this means that a spiral is a better alternative. Multilayer coils have the problem of interlayer capacitance, so when multiple layers are needed the shape needs to be radically changed to a short coil with many layers so that the voltage between consecutive layers is smaller (making them more spiral like).
The river gone, so why go on?
And the sun dissolves like [an August? a mongoose?!]
No [offence?] to the hummingbirds
No reward from the sun
On it was a hover-firefly
Even ??? been there alive
All hummingbirds must die
Do you believe in debts?
Are you ??? some [ghosts? guests?]?
I want to [believe?]
It's a certainty of animals
I want to go among the [birds?]
I will smoke across an ocean, a lagoon of fish
For fly with suicide's-eye birds
I'm so tired of the [seasons?] and the breeze and the
river
??? wasps [pollinating sores? pollen and mutating
exhaust?]
And their altered states of [merriment?]
Want to go under ???
I want you and [I need you? I'm near you?] but I can't
find you
I'm allergic to disease
Christ [I wanna be quick? Madonna, be quick?] with
[hummingbirds?] keeps falling to his knees
And then I reach the station in the heaven of glass
I'll say a little prayer for you
Then I'll cut off the heads of the birds that fly
All hummingbirds must die
All hummingbirds must die
There is no wrong, so why go on?
