    Almost, you'll need to double this up so there are two complete rings with arrowheads going around the iron core.

    Just the green arrows, but draw them twice over.

    Edit: also I think that at A-Level the examiners aren't too bothered which way the arrows go, as long as they're both clockwise or both anticlockwise (i.e. not contradictory). But do check with your exam board on this.

    draw the flux going through the iron laminate core all the way round... Flux 'likes' to go through iron a lot more than air/vacuum and most other materials.
