Mathematically, the induced emf is given by

where (ϕN) is the number of ux linkages of the circuit in Weber-turns. Flux linkages mean the sum of ux lines linking with each turn of the circuit, so that the number of ux linkage is equal to the product of the ux and the number of turns of the circuit linked.
