For a project, i want an electromagnet with a hollow cylindrical space of 60mm(something Iike as shown in attached image) which can produce a force of 1000N inside this hollow space on a ferromagnetic object? Is this possible and how should i design or get such a type of electromagnet?

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.

Do you have a similar question?
