I reversed the process.
The coercive force, or coercivity, of a material is that reversed magnetic force which, while it is acting, just suffices to reduce the residual induction to nothing after the material has been temporarily submitted to any great magnetizing force.
As regards the higher temperatures, the chief point of interest is the observation that the curve of magnetization for annealed cobalt shows a small depression at about 450°, the temperature at which they had found the sign of the length-change to be reversed for all fields.

In the early municipal constitution ex-magistrates passed automatically into the senate of their town; but at a later date this order was reversed, and membership of the senate became a qualification for the magistracy.
When the switch S is closed, K acts simply as a commutator or current-reverser, but if K is thrown over from right to left while S is opened, not only is the current reversed, but its strength is at the same time diminished by the interposition of the adjustable resistance R2.
If Annie's abductor was still operating, that literally reversed the odds that we'd knock heads with him if he remained active!

The dey of Algiers, who saw the opening, reversed the order of his squadron, and fell on the right of the centre.
When work is done against these forces no full equivalent of potential energy may be produced; this applies especially to frictional forces, for if the motion of the system be reversed the forces will be also reversed and will still oppose the motion.
A small permanent magnet is always liable to become demagnetized, or have its polarity reversed by the action of lightning.
In this the tongue of the relay is kept over to the spacing side by means of a current flowing in one direction, but on the depression of the signalling key the current is reversed, moving the relay tongue over to the marking side.
Were childishly wayward and capriciously autocratic; both were recklessly indifferent to the feelings, convictions and wishes of those around them; both took a passionate interest in the minutiae of military affairs; as Peter had conceived a boundless admiration for Frederick the Great, so Paul conceived a similar admiration for Napoleon, and both suddenly reversed the national policy to suit this feeling; both were singularly blind to the consequences of their foolish conduct; and both fell victims to court conspiracies which could be in some measure justified, or at least excused, on patriotic grounds.
Showed, however, that his father's policy of Russification was neither to be reversed nor to be abandoned.
6 This was reversed, on the 8th of June, by 238 votes to 191, after a patient exposition by M.
With knowledge then of the heats of formation of the substances involved in any chemical action, we can at once calculate the thermal effect of the action, by placing for each compound in the energy-equation its heat of formation with the sign reversed, i.e.
The case was tried in 1329 and decided against Lymington, but in 1750 the judgment was reversed, and since then the petty customs have been regularly paid.
- Tube-dwelling with body divided into thorax and abdomen marked by the setae, which are reversed in position in the neuropodium and notopodium respectively in the two regions.
Mirabeau first set to work to get the sentence of death still hanging over him reversed, and by his eloquence not only succeeded in this but got M.
He stated that his people, after giving warning in 5824 that they would consider protection the policy of the Government, had gone into protected manufactures, and he now asked that that policy be not reversed to the injury of his constituents.
In the effort to reduce the practice of economy to a fine art he arrived at the conviction that the less labour a man did, over and above the positive demands of necessity, the better for him and for the community at large; he would have had the order of the week reversed - six days of rest for one of labour.
On the other hand, we may imagine the processes due to the electrical transfer to be reversed by an osmotic operation.
In ordinary cases possible changes in the concentrations only affect the electromotive force by a few parts in a hundred, but, by means such as those indicated above, it is possible to produce such immense differences in the concentrations that the electromotive force of the cell is not only changed appreciably but even reversed in direction.
If the operation is again reversed, the upward course will be nearly, but not exactly, of the form shown by the line d c a, fig.
When a hysteresis curve is to be obtained, the procedure is as follows: The current is first adjusted by means of R to such a strength as will fit it to produce the greatest + and - values of the magnetizing force which it is intended to apply in the course of the cycle; then it is reversed several times, and when the range of the galvanometer throws has become constant, half the extent of an excursion indicates the induction corresponding to the extreme value of H, and gives the point a in the curve fig.
When the magnetizing current is twice reversed, so as to complete a cycle, the sum of the two deflections, multiplied by a factor depending upon the sectional area of the specimen and upon the constants of the apparatus, gives the hysteresis for a complete cycle in ergs per cubic centimetre.
A small coil of fine wire, connected in series with a ballistic galvanometer, is placed in the field, with its windings perpendicular to the lines of force, and then suddenly reversed or withdrawn from the field, the integral electromotive force being twice as great in the first case as in the second.
The most interesting of his discoveries, now generally known as the " Wiedemann effect," is the following: If we magnetize longitudinally a straight wire which is fixed at one end and free at the other, and then pass an electric current through the wire (or first pass the current and then magnetize), the free end of the wire will twist in a certain direction depending upon circumstances: if the wire is of iron, and is magnetized (with a moderate force) so that its free end has north polarity, while the current through it passes from the fixed to the free end, then the free end as seen from the fixed end will twist in the direction of the hands of a watch; if either the magnetization or the current is reversed, the direction of the twist will be reversed.
The twist effect exhibited by iron under moderate longitudinal magnetization has been called by Knott a positive Wiedemann effect; if the twist were reversed, the other conditions remaining the same, the sign of the Wiedemann effect would be negative.
Bidwell 2 accordingly found upon trial that the Wiedemann twist of an iron wire vanished when the magnetizing force reached a certain high value, and was reversed when that value was exceeded; he also found that the vanishing point was reached with lower values of the magnetizing force when the wire was stretched by a weight.
Thermal) is reversed, but the longitudinal effects are independent of the direction of the field.
Convenient arrangements have been introduced whereby the coil is reversed or withdrawn from the field by the action of a spring.
If the external electromotive force exceed that of the cell by ever so little, a current flows in the opposite direction, and all the former chemical changes are reversed, copper dissolving from the copper plate, while zinc is deposited on the zinc plate.
But many Roman Catholic writers, though they yield a practical obedience to the papal decision, have adduced good reason why it should be reversed (Cognat, p. 451).
The ordinary distinction between note and letter is reversed in diplomacy.
By a similar process the board's decision in favour of the election of Republican presidential electors was nullified, and the Democratic electors were declared the successful candidates; but the electoral commission, appointed by Congress, reversed this decision.
