ere-turns,and experiment would show that the same magnetomotive force isobtained with a current of 100 amperes flowing around 1 turn, 25amperes circulating in 4 turns, or 1 ampere passing through 100 turns.In each case there are 100 ampere-turns. To calculate the value of the magnetomotive force in… … Fig. 10. Toroid and Exploring Coil m. m. f. = yV IT = 1.257 IT (1) Reluctance. Now take a number of wooden rings all of the samecross-section, but of different diameters, and wind upon each thesame number of turns of wire evenly distributed, as in Fig. 10. Ifan exploring coil is placed upon each…
