No. Magnetic field strength depends on current times number of turns, times a factor which depends on the nature of the magnetic materials involved and their geometry.
Voltage plays no part in creating the magnetic field, but a given amount of voltage is required to drive the current through the coil, and this has a bearing on the efficiency, in terms of field strength per watt of heat dissipated.
Using many turns of thin wire means a strong field with a relatively small current, but with a high resistance, so a high supply voltage is needed. Using thicker wire will mean less turns will fit on the core, so more current needed for the same field strength. However, proportionately less voltage is required because of the lower resistance. So, the wire gauge mainly determines the operating voltage, the power requirement being much the same regardless.
