B
The magnetic field (and thus the force) of an electromagnet is directly proportional to the current and the number of turns of wire (for a solenoid B ∝ μ (N/L) I, so increasing I or N increases the field). Core material (permeability) and geometry also matter, but "type of force" or core length are not the primary direct factors listed.
