This wonderful instrument consisted of a magnet made of a small fragment of watch-spring, suspended in a horizontal position by means of a thread of fine silk, close to a coil of fine wire.
In such a case the primary part of the coil is made of many turns of fine wire, so that little current passes through it, while the secondary part is but one or two turns of thick bar.
In this circuit is placed the instrument, together with a coil made of a very long length of fine wire so that it has a very great resistance.
Now a fine wire is inserted in the fuse, and when everything is in readiness, the ends of the wire are attached to the poles of a distant battery and the heat developed in the wire ignites the fuse.
The principle of practically all galvanometers is as follows:-- A closely wound coil of fine wire free to rotate is suspended as in Figure 233 between the poles of a strong magnet.
This comparison is still more striking when we take into consideration the experiment of Mr. Harris, in which he stretched a fine wire across a glass globe, the air within being rarefied[A].
This is a large hollow drum, the outer surface of which consists of a fine wire cloth, the interior of the washer being fitted with specially curved scoops.
The pulp and water are pumped into a wooden box in which revolves a large hollow drum, the surface of this drum consisting of a fine wire cloth of about 60 or 70 mesh.
The effect is produced by means of a raised design sewn or soldered to the surface of the mould, the design being fashioned out of fine wire.
The mould is a rectangular frame of mahogany upon which is stretched tightly a fine wire cloth, the surface of the latter being kept flat by a coarser wire cloth fixed underneath, supplemented by wedge-shaped pieces of wood.
Each magnet bears on its end nearest the diaphragm a winding of fine wire, the two ends of each of these windings being joined by means of a two-wire line.
Where the winding is of fine wire, it is always well to reinforce its ends by a short piece of larger wire.
Ordinarily the coefficient of space utilization is greater for coarse wire than for fine wire, since obviously the ratio of the diameter of the wire to the thickness of the insulation increases as the size of the wire grows larger.
The normal path from the line to the apparatus is through a small coil of fine wire imbedded in sealing wax.
It is also a good plan to place a fine wire strainer on the napkin to catch the shells and scum.
Cut a slice or two from each, and extract the juice with a lemon drill; strain the juice through a fine wire strainer to remove the seeds and bits of pulp, and pour it over the sugar.
Bake nice potatoes till perfectly tender; peel, mash thoroughly, and to each pint allow the yolks of two eggs which have been boiled until mealy, then rubbed perfectly smooth through a fine wire sieve, and one half cup of rich milk.
Most of these are based on the principle of incandescence, the current heating a fine wire or other conductor of high resistance in passing through it.
The potato pulp must be now elutriated upon a fine wire or hair sieve, which is set upon a frame in the mouth of a large vat, while water is made to flow upon it from a spout with many jets.
I pass a long thread through the eye-hole E of the bolt, and then draw the two ends through the tube by a fine wire with a hook to it, one end on one side of the cross wire D, and the other end on the other side.
The primary coil is wound on a bolt which serves as the core, and on this coil is wound the secondary which consists of many turns of fine wire.
By using the coil of fine wire as the primary, we can lower the voltage and increase the strength in the same proportion.
Their coils are usually wound with many turns of fine wire, so that a feeble current will move its nicely adjusted armature.
If a ferrule is not at hand, a fine wire can be wound around the end to prevent the pole from splitting.
The point of the latter is sharpened and then the bamboo wound with waxed twine, or fine wire, to prevent its splitting.
Illustration: The Shape of the Hinge, and the Manner of Attaching It to a Cover or Door] Shoestring End When the tips slip from shoelaces, new ones may be readily made of fine wire.
If, on the other hand, the coil be one of fine wire, in many convolutions, as it requires more pressure, or E.
This makes, in all, about 2,500 turns of fine wire.
You will find it a very tiresome and troublesome job, however, to wind on 12 or 15 hundred turns of fine wire by hand.
The Secondary Coil should be made of a large number of turns of fine wire.
The primary coil~ P, consisting of many turns of fine wire, is connected across the main conductors C and D, coming from the alternator.
When constructed as a ~voltmeter~, both coils are wound with a large number of turns of fine wire, making the instrument sensitive to small currents.
When constructed as a ~wattmeter~, one coil is wound so as to carry the main current and the other made with many turns of fine wire of high resistance suitable for connecting across the circuit.
Then we connect a good deal of fine wire in series with the instrument for a reason which I'll tell you in a minute.
That is why voltmeters of this kind are made out of a long piece of fine wire or else have a coil of fine wire in series with the current-measuring part.
Suppose a piece of fine wire is fastened at the two ends and that there are binding posts also fastened to these ends of the wire so that the wire may be made part of the circuit where we want to know the electron stream.
Cover a piece of fine wire, about three inches long; affix a small piece of green wax, pressed into a point by the side of, and at the end of, the said points.
A foundation is formed at the end of a piece of fine wire, the pistil attached, and the stamina encircling the same.
Cover a piece of fine wire, about four inches in length, with light green wax, mould to the end a strip of lemon wax, to which affix first the pistil and subsequently the stamina.
A short coil galvanometer has a coil consisting of a few turns of heavy wire; a long coil galvanometer is wound with a large number of turns of fine wire.
When constructed as a wattmeter, one coil is wound so as to carry the main current, and the other made with many turns of fine wire of high resistance suitable for connecting across the circuit.
An ammeter coil consists of a few turns of heavy wire (when designed to carry the full current), while a voltmeter coil is wound with many turns of fine wire.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "fine wire" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
