Final answer:

Adding more coils to the wire increases the strength of the magnetic field. Changing current flow direction or stopping the current does not enhance the field.


Explanation:

Adding more coils to the wire increases the strength of the magnetic field of a coiled electrical wire. This is because the magnetic field is proportional to the winding density multiplied by the current. By increasing the number of windings in the coil, you are increasing the winding density, leading to a stronger magnetic field.

Changing the direction of the current flow or stopping the current does not directly increase the strength of the magnetic field. Straightening the wire would reduce the winding density and therefore weaken the magnetic field generated by the coil.
