To increase the strength of the magnetic field generated by a coiled electrical wire, you would:
**Add more coils to the wire.**
Adding more turns or coils increases the strength of the magnetic field, as each additional coil contributes to the overall magnetic field produced around the wire.
Straightening the wire and stopping the current would not enhance the magnetic field, and changing the direction of current flow merely reverses the magnetic field direction without increasing its strength.
