What reading level is Elements of Electricity for Technical Students book?
To quickly assess the difficulty of the text, read a short excerpt:
Example. How many ampere-turns are required to set up a flux of 1, 200, 000 lines in a cast-iron circuit 200 cms. Long, with a cross-section area of 300 sq. Cms. ?
4 000 gausses.
From table, in Appendix, for relation of B to H in cast-iron, H (for B of 4000) -8. 5; o c \/ 200 NI = = 1350 ampere-turns.
The design of an electro-magnet includes many details in addi- tion to the number of ampere-turns. The size of wire and the amount of surface required for radiation are two factors which affect th...e design fully as much as the ampere-turns. 1 1 For practical directions in the design of electro-magnets, the Varley Electro-Magnet Co. Of Jersey City has published a most excellent book- let. It contains a mass of information and practical formulas which will be found invaluable to one designing a magnet for a definite use, MAGNETIC FIELD DUE TO A CURRENT 147 Solve the following problems by use of BH tables in Ap- pendix.
Problem 24-6. A wrought-iron magnetic circuit has a length of 65 cms. How many turns must be wound on it to give a flux den- sity of 6000 gausses if the current through the turns is .
