your electromagnet is an inductor powered by a battery with constant potential   V. The magnetic field is proportional to the intensity running on the wires.   B  ∝  I. We know:   V  =  R  I, where   R is the resistance of the inductor. Its a very simple model as you can see...For a small variation of temperature from initial temperature       T    0  , the resistance can be approximated with a linear relation:  R  =  R  (      T    0    )      [    1    +    α          (      T      −              T        0            )        ]  find   α for a given material arround       T    0   that you want to work with. So, in the vicinity of       T    0  , and with the temperature coeficient   α measured/given, we can now conclude:- If   α  &amp;gt;  0, resistance increases, current decreases, magnetic field decreases.- If   α  &amp;lt;  0, resistance decreases, current increases, magnetic field increases.- If   α  =  0, resistance decreases, current increases, magnetic field increases.Temperature coeficient arround       T    0    =  293  K
