Antimagic field

The caster created a 10 foot sphere radius around it that removed the magical forces of the universe around it. The sphere made all magics within non existent, as it followed the caster all spells would seize and magic weapons became mundane. The sphere could not be dispelled or cancelled by another animagic field and if a magic item left the field it would regain its magical properties. Any summoned creatures would disappear in the field but when the field left the space where the creature was it would reappear.
