A higher voltage battery makes the electromagnet stronger.
Reason: The magnetic field of a coil is proportional to the current (B ∝ N·I). With a fixed coil resistance, a higher voltage produces a higher current (Ohm’s law I = V/R), so the electromagnet is stronger (until limited by core saturation, coil heating, or battery internal resistance).
