nsuch a ring and electric current passedthrough the coils the ring will be stronglymagnetised without poles. If we winda second coil over the first and makeand break the electric current of thefirst coil, we shall get induced current in the second coil, due to themagnetic flux in the iron ring.… … second coil by pullinir the two halfs apart. In all electro-magnetswe have a current-carrying coil or coils of wire and an iron coreto be magnetised, in which there are, in most cases, gaps, acrosswhich the lines of magneticforce pass from pole topole, as in Fig. 105. A wirecarrying a current is…
