﻿454 Prof. Lyle and Mr. Baldwin on Propagation of 



11. C, the next specimen tested, was a long thick iron 

 wire. Three series o£ experiments were made with it for 

 three different frequencies and approximately the same 

 initial flux. 



Details of Specimen C. 



A straight iron wire. 

 Length = 324 cms. Diameter = '398 cm. 

 Section = 0-1244 cm 2 . 

 Specific resistance = 1*006 x 10 4 . 



Magnetizing solenoid and search-coils the same as 

 were used with specimen A.

In Tables XIV., XV., and XVI. are given the analysed 

 results of the alternating flux experiments with this specimen, 

 and in Table XVII. the results with the continuous flux.
