Defn: An instrument for recording and reproducing sound by local magnetization of a steel wire, disk, or ribbon, moved against the pole of a magnet connected electrically with a telephone receiver, or the like.
Magnetic susceptibility (Physics), the intensity of magnetization of a body placed in a uniform megnetic field of unit strength.
The lag is not in the iron, but in the magnetizing current, and the current being retarded, the magnetization is of course retarded also.
In short pieces, where these mutual actions are feeble or almost absent, the magnetization is less stable, and disappears almost instantly on the cessation of the magnetizing force.
There are also electricians who will tell you that when magnetization is suddenly evoked in an iron bar, there are induction currents set up in the iron which oppose and delay its magnetization.
That they oppose the magnetization is perfectly true, but if you carefully laminate the iron so as to eliminate eddy currents, you will find, strangely enough, that the magnetism rises still more slowly to its final value.
In long pieces of iron the mutual action of the various parts tends to keep in them any magnetization that they may possess; hence they are less readily demagnetized.
The distribution of the magnetizationhas therefore become unsymmetrical, and the iron core is no longer in equilibrium in the magnetic field.
Menges says that the residual magnetization is sufficient in his machine to start the rotation by itself.
His paper on "Magnetization of Light and the Illumination of the Lines of Magnetic Force".
He spoke as if he thought the lines of magnetic force had been rendered luminous by the light rays; for, he announced his discovery in a paper entitled, "Magnetization of Light and the Illumination of the Lines of Magnetic Force.
To the same cause, he attributes the magnetization of iron crosses attached to steeples, towers, etc.
If steel is magnetized, it remains so; but soft iron loses practically all its magnetism as soon as the cause of magnetization is withdrawn.
It is fortunate for us that this is so, since on the rapid magnetization and demagnetization of soft iron depends the action of many of our electrical mechanisms.
The condenser diminishes the period of extinction very greatly, while lengthening the period of magnetization after the "make" of the primary current, and so decreasing the strength of the reverse current.
In this case it will assist the battery to discharge when the direction of the field magnetization is changed.
The shunt coil produces a field which opposes the field produced by the series coil, the resulting magnetization being, in direction and amount, the resultant of the two field strengths.
The adjustments are so made that when the normal dynamo current is passing through the series coil, the shunt field just neutralizes its effect, and the resultant magnetization is zero.
This interrupted flow of electricity through the primary circuit provides the intermittent magnetization of the core necessary to produce the secondary electromotive force.
In this break the magnetization of the iron core by the primary current is made to attract an iron block fixed to the end of a spring, in such a way that two platinum points are separated and the primary circuit thus interrupted.
He resurveyed the experiments of Cavendish, Priestley, and other pioneer electricians, and established a theory of molecular magnetization which provided a working formula to explain electrical currents and magnetic fields.
This cross magnetization of the armature tends to distort the field produced by the field magnets, the effect being known as armature reaction.
If the magnetization curve of the particular quality of iron used for armature plates be known, the hysteresis loss may be calculated approximately.
More accurately, the permeability is the ratio existing between the amount of magnetization and the magnetizing force which produces such magnetization.
In these curves the ordinates represent the total magnetization =B=, while the abscissas represent the magnetizing force =H=.
The receiver of the Automatic Electric Company just discussed employs but a single electromagnet by which the initial magnetization of the cores and also the variable magnetization necessary for speech reproduction is secured.
The totalmagnetization resulting from a magnetizing force is called the magnetic flux, and is analogous to current.
The iron should, if possible, be worked at that density of magnetization at which it has the highest permeability in order to obtain the maximum impedance effects.
In permeability curves the total magnetization of the given pieces of iron are plotted as abscissas, while the corresponding permeabilities are plotted as ordinates.
Increasing the strength of the magnetizing field, gives strongermagnetization to the iron up to a certain point.
When iron exhibits its greatest magnetization it is said to be saturated.
It was only during the time of magnetization or demagnetization that these effects were produced.
The magnetization of a bar of steel or iron, according to this theory consists in establishing within the metal by induction a series of electrical currents, all revolving in the same direction at right angles to the axis or length of the bar.
The induced currents declared a change of condition only, and they vanished the moment the act of magnetization or demagnetization was complete.
This apparatus, then, constitutes a genuine electric servo-motor in which the current is never interrupted nor modified in quantity or direction, no more indeed than the magnetization developed in the soft iron cylinder.
When the generated frequency of the machine is equal to the difference of the excitation and rotation frequencies, the magnetization of the machine is higher under a non-inductive load than under no load.
The direction of the resultant magnetization is indicated by the arrow in each figure.
The softest iron obtainable is used for the core, and a low degree of magnetization is employed.
A is 4 lines, and of B, 9 lines, the resultant magnetization having rotated 22½°.
The rotation of the resultant magnetizationis clearly seen by following the arrow through its successive positions.
The main winding 1 produces the initial field magnetization as heretofore; the auxiliary winding 2 controls the power factor or "compensates" the motor.
By following the arrow through the successive positions the rotation of the resultant magnetization is clearly seen.
A phase difference also appears when the magnetizationis too strong.
Thus there is hysteresis in the relation of magnetizationto magnetic force.
The dependence of the intensity of magnetizationon the strength of the current was subsequently investigated (Pogg.
The curve which delineates the relation of H and B is called the magnetization curve for the material in question.
He then propounded his brilliant hypothesis that the magnetization of iron was due to molecular electric currents.
The oscillating discharge of a condenser had been inferred by Henry as long ago as 1842 from his experiments on the magnetization produced in needles by the discharge of a condenser.
In the cyclical reversal of magnetization of iron we have two modes to consider.
The periodical breaking of the circuit produced by the transmitter causes a variation in the magnetization of the iron cores of the five receivers and makes the firwood strips vibrate energetically.
Take away the iron core, and the energy of magnetization of the air or ether core expends itself on the wire of the primary and, possibly, also on the dielectric of the condenser to some extent.
OErsted discovered the deflection of the magnetic needle, and Arago and Sturgeon the magnetization of iron by the electric current.
In repeating Faraday's experiment on the magnetization of light, we had, in the first instance, our Nicols crossed and the field rendered dark, a flash of light appearing upon the screen when the magnet was excited.
I refer to the experiment which Faraday, its discoverer, called the 'magnetization of light.
To render our series of comparisons complete, we must demonstrate the magnetization of heat.
Faraday called those bodies which were repelled by the poles of a magnet, diamagnetic bodies; using this term in a sense different from that in which he employed it in his memoir on the magnetization of light.
In fact Faraday had notions regarding the magnetization of light which were peculiar to himself, and untranslatable into the scientific language of the time.
His third great discovery is the Magnetization of Light, which I should liken to the Weisshorn among mountains--high, beautiful, and alone.
While once sauntering with him through the Crystal Palace, at Sydenham, I asked him what directed his attention to the magnetization of light.
In November, 1845, he announced his discovery of the 'Magnetization of Light and the Illumination of the Lines of Magnetic Force.
The induced currents declared a change of condition only, and they vanished the moment the act of magnetization or demagnetization was complete.
Both in the process of magnetization and demagnetization.
It is converted into heat in changing the positions of the molecules during magnetization and demagnetization.
The magnetic permeability decreases as themagnetization increases.
For all practical purposes, magnetic saturation may be defined as: That point of magnetization where a very large increase in the magnetizing force does not produce any perceptible increase in the magnetization.
The supposed magnetization of light by Faraday has already been mentioned.
On the Magnetizationof Light, and the Illumination of Magnetic Lines of Force: by Michael Faraday, D.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "magnetization" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: electromagnetism; hysteresis; magnetism
