Soft iron is iron which becomes instantly magnetized by induction when exposed to any magnetic force, but has no power of retaining its magnetism.
Any bar of soft iron can be made temporarily into a magnet by twisting round it a few turns of a wire in circuit with the poles of a battery.
The wheel, made of soft iron, and toothed on its circumference, revolves at a short distance from the pole of a magnet.
Such a magnet has what is known as a north pole and a south pole, the one attractive and the other repulsive of steel or soft iron.
The electron refers to electro-magnets; an electro-magnet is simply a piece of soft iron with a coil of insulated wire wound around it.
The line of march ended in a short length of fine wire wound around a piece of soft iron to form an electro-magnet.
While we render an important aid to man by providing this permanent magnet for his compass, you will find that a very great deal of our assistance to man in his everyday life depends upon our behaviour in soft iron electro-magnets.
A piece of iron inserted where the core was, would instantly become a magnet, and when the insulated wire is wound around a soft iron core, and the core is left in place, we have at once what is known as an Electro-Magnet.
Previous to the investigations of Professor Henry, in 1830, only the theory of causing a core of soft iron to become a magnet was known, and the actual magnet, as we make it, had not been made.
He constructed a telephone in which a rod of soft iron, about six feet in length, was used instead of a permanent magnet.
It consists in this, that while a current of galvanism is passing through a copper wire A B, it is magnetic, it attracts iron filings and not those of copper or brass, and is capable of developing magnetism in soft iron.
Sturgeon was of the same kind as that used by Arago; instead however, of a straight steel wire inclosed in a tube of glass, the former employed a bent wire of soft iron.
At D we have the evident polarity induced by the earth's directive influence when a soft iron rod is held in the magnetic meridian.
No, every piece ofsoft iron brought near a magnet becomes by induction itself a magnet.
Does the magnetism imparted to a piece of soft iron, or steel, by contact with a natural magnet, remain permanent in their substances?
Is it necessary that absolute contact should take place between a magnet and a piece of soft iron to render the latter a magnet?
It can be made of either brass or soft iron, but, for the sake of convenience, the description will be for one made of brass.
The jeweler demagnetizes a watch in the following way: He has a piece of soft iron with an opening cut in its center of such shape and size as to receive the watch, and with a fine wire wound about it.
Imagine a rod of soft iron of any size to be wound with a coil of wire, the ends of the wire to be so left that they may be connected with a galvanic battery.
N' and S' are short rods of soft iron fastened into a yoke-piece Y, also of soft iron.
The piece, A, is called its armature, and is made of soft iron, while the magnet itself should be made of the best steel, properly hardened.
To study the inductive action of a magnet upon a piece of soft iron.
If a rod or core of soft iron I be suspended by fibres from a support, it will be sucked towards the middle of the coil as into a vortex, by the circular magnetic lines of every spire or turn of the coil.
Again, if we magnetise a piece of soft iron we can destroy its magnetism by striking it so as to agitate its atoms and throw them out of line.
Nevertheless, if we put the atoms of soft iron under a strain by bending it, we shall find it retain its magnetism more like a bit of steel.
A mixture of 100 parts of soft iron, and 2 of lamp black, melts as readily as ordinary steel.
Calcareous spar occurs in colourless crystals or crystalline masses; dissolves with effervescence in muriatic acid; is scratched by soft iron, but not by the nail; specific gravity 2.
The marble saw is a thin plate of soft iron, continually supplied during its sawing motion, with water and the sharpest sand.
The magnetic property is very readily imparted (by induction, as it is called) to soft iron, but when the iron is removed from the magnetising body, it parts with the virtue as fast as it acquired it.
These plates, formed of a true plating of steel upon a bed of soft iron, have been much in vogue in the English navy, and seemed as if they were to be adopted about everywhere.
By placing both coils, A, upon the bundle of soft iron wires, G, connecting one of them with the terminals of the battery, as shown in Fig.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "soft iron" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
