I know that magnetic field lines are radial in a galvanometer because of the soft iron core. My question is if they are indeed radial then they should meet at the centre of the cylindrical iron core, but this is not possible as field lines cannot meet, so how will the magnetic field lines be within the soft iron core. This is the link for a figure of galvanometer field lines. https://www.google.com/search?q=galvanometer+field+lines&tbm=isch&ved=2ahUKEwj-oY_wivnfAhVSFSsKHdXVDWYQ2-cCegQIABAC&oq=galvanometer+field+lines&gs_l=mobile-gws-wiz-img.3...824.5338..5470...3.0..0.230.2496.0j13j1......0....1.........0i67j0j0i5i30j0i8i30j0i24j30i10.Ys1A9SxYYp0&ei=1bFCXL7jDdKqrAHVq7ewBg&bih=706&biw=393&client=ms-android-xiaomi&prmd=ibnv#imgrc=HVyyH_TLjYPXCM
Also please answer how does placing a soft iron core make the magnetic field lines radial.
