How would you compare the magnetic field generated by a simple length of wire to the magnetic field generated by a coil of wire?

The coil generates a stronger magnetic filed

The coil generates a weaker magnetic field

The field generated by the coil has different polarity than the field generated by the length of wire

The coil generates a field that attracts iron objects; the length of wire generates a field that attracts silver objects.
