What benefit is gained by the addition of the iron core in an electromagnet

The Iron core simply assists in the translocation of electron molecules being knocked out of place drawing another electron in which creates a greater force of magnetism. So, in conclusion it amplifies the magnetic attraction between the electromagnet(s).

This is what i found “in a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. early gas turbine engines used a single chamber known as a can type combustor. today three main configurations exist: can, annular and cannular (also referred to as can-annular tubo-annular).” i hope this you for what your looking for. can you plz mark me brainliest?
