    Find Flux Density in Iron Ring: 1A Current, 5cm Length, 200 Turns, 1mm Gap

    hi dears, sorry for late reply acctualy I was out of city as per your instructions I had put the area as a A and I find out these total reluctance 24.3 A(area)AT/wb magnetising force H = 40.81*10^2 AT/m F = .5020 A(area) AT/wb now to find out the flux or resistance...

    Find Flux Density in Iron Ring: 1A Current, 5cm Length, 200 Turns, 1mm Gap

    hi dears but how can we put 2 unknown in a same equation for example for reluctance we need area S= l/ mu * A. and same for flux weber= NI / l/munot *mur*A

    Find Flux Density in Iron Ring: 1A Current, 5cm Length, 200 Turns, 1mm Gap

    an iron ring of mean length 5 cma has an air gap of 1mm and a winding of 200 turns. If the permeability of iron is 300 when 1A current flows through the coil find the flux density. its answer is 94.2 mWb/m^3 kindly help how I would drive it
