It works like a kind of circular horseshoe magnet. This kind of electromagnets holds iron plates that complete the "magnetic circuit" between the faces of the inner and the outer circumference.
At saturation, the holding power depends on the surface area of these faces. Just look in catalogs if you want to hold a weight of 100 kg.
There is almost no field in the hollow space.
