Let us consider the effect that a magnetisingforce produces on a bar of soft iron.
We may express the relation between cause and effect by a curve in which the abscissa represents the magnetising current, and the ordinate the magnetisation produced (fig.
But Bidwell finds that as the magnetising force is pushed to an extreme, at a certain point elongation ceases and is succeeded, with further increase of magnetising force, by an actual contraction.
The force which produces that molecular deflection, to which the magnetisation of the bar is immediately due, is the magnetising current flowing round the solenoid.
The stronger the magnetising force, the nearer do the molecules approach to a perfect alignment, and the greater is the induced magnetisation of the bar.
In the interior of this coil are placed a number of little bundles of fine iron wire wound round with two coils, a fine wire coil which is a magnetising coil, and a thicker wire coil which is a demagnetising coil.
The second class comprises the magnetic kumascopes which depend upon the action of an electrical oscillation as a magnetising or demagnetising agency.
Secondly, the magnetising current is stopped, and soon after that the secondary coil is unshort-circuited and connected to the galvanometer, and remains in this condition during the remainder of the revolution.
The pole pieces of the coherer tube are made of iron, and they are enveloped in magnetising coils traversed by an alternating electric current.
In magnetising the needle, I have supposed the point to be the last to quit the marked end of the magnet; the point of the needle is a south pole.
Such was the process of magnetising recommended by Deleuze.
About the same time that Valentine Greatraks was thus magnetising the people of London, an Italian enthusiast, named Francisco Bagnone, was performing the same tricks in Italy, and with as great success.
One of the effects which electricity can be made to produce is the magnetising of steel bars to form the ordinary and well-known permanent magnets which are used in ships' compasses, &c.
Four of the helices had their similar ends bound together by wire, and the two general terminations thus produced connected with the small magnetising helix containing an unmagnetised needle (13.
Thus, if the battery communications were first made, and then the wire under induction connected with the indicating helix, no magnetising power was there exhibited.
Schweigger of Halle discovered that this deflecting force was increased when the wire was wound several times round the needle, and thus he invented the magnetising helix.
Thus the molecular upset and rearrangement, in a magnetic substance under increasing magnetising force are inferred from the curve obtained by means of appropriate magnetometric or galvanometric methods.
Fischer, having adopted the like mode of magnetising the steel, which he also carefully heated, has made magnets of from 1 to 3 lbs.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "magnetising" in a variety of sentences. We hope that you will now be able to make sentences using this word.
