ment ata given temperature may be considered fixed. Within the limits ofatmospheric variations, the effects produced are then proportionalto changes of temperature. If il/^ and M are the moments of oneand the same bar at the temperatures 0° and f, we may put M=M,{\-at), a being a coefficient the… … 235] METHODS OF MAGNETISATION 329 merely to place it in a magnetic field ; the particles must beshaken, as it were, so as to overcome the coercive force. Insteadof causing a uniform field to act upon it, it is better to act insuccession on the various parts. At the present day electriccurrents are…
