We can increase the magnetic force by either by increasing the current or by increasing the no. of turns.

Magnetic coercivity is proportional to current through the coils. Considering Ohm's law I=v/r , you can see that while R is constant, you can change V (voltage). Small increases in voltage through the same windings will increase force.

Increasing the current without doing any physical changes or increase the frequency

Increase the number of windings or increase the current.
