To compare the strengths of the magnetic fields in two sets of wire coils, the important data needed are:
**the number of loops in each coil and the current in the wire.**
This is because the strength of the magnetic field created by a coil of wire (solenoid) is directly proportional to both the number of loops (turns) and the amount of current flowing through the wire. Thus, this option contains the necessary factors for comparing the magnetic field strengths effectively.
