For very large velocities we have =JLfdxv = d-S- ft., , Y 27rjd£ 2irr(f~v2) o which formula is not applicable at infinity.See Fig. 11. The formulae here developed are illustrated by Fig. 11,pp. 112 and 113. The assumptions on which the diagramsare based are the following:— The plate is made of copper (thus tc= 227,000) and hasa thickness 2 mm. (thus k= 113,500). The distance of thepole from it is 30 mm. The values of ty marked give absolutemeasure when the strength of the pole is 13,700 mm-mgr-/sec.In Fig. 11, a and l, p. 112, the velocity of the pole is5 m/sec(a = 5000); here a represents the phenomenon whenself-induction is neglected, h when it is taken into account. Fig. 11 c represents the phenomenon for a velocity of100 m/sec, calculated by means of the formula for large valuesof
