Yes I have to make my answer 20 characters long so imma just type this sentence
Electromagnet is in form of solenoid
and the magnetic field due to solenoid is given as
here

so when we increase the current in electromagnet the magnetic field of the solenoid will increase
this will increase the strength of the electromagnet
so the answer would be
<em>INCREASE</em>
