Forcefield is a defensive buff which gives the Enhanced Shield bonus, and benefits from Strong Magical Shields.
The forcefield gives you a base bonus of +10 Defence and Protection, or +15 if the spell is enhanced. Your green magic is then applied as a percentage modifier to the base bonus (eg green magic 100 would give +100%, thus doubling the base bonus). After applying your green magic modifier, you get a further +5 Defence and Protection per rank.
