The correct answer among the responses is: by increasing the current in the wire.
by straightening the wire?
I apologize for the confusion. Strengthening the magnetic field in a wire is not related to straightening the wire. The correct answer among the provided responses is: by increasing the current in the wire. Increasing the current flowing through a wire will strengthen the magnetic field around it.
