Which of the following occurs when the strength of the current flowing through a wire is increased?

A. The direction of the field changes.
B. The magnetic force is created.
C. The magnetic field is increased.
D. The magnetic field is decreased.

A). No. The direction of the field depends only on the direction of the current, not on its magnitude.
B). No. The magnetic force was there as soon as there was any current. It didn't begin when the current increased.
C). Yes. The magnetic field is increased. More current causes a stronger magnetic field.
D). No. The magnetic field isn't decreased. More current causes a stronger magnetic field.

Increasing the current through a wire strengthens the magnetic field generated by it. The direction of the field remains unchanged, but its strength increases proportionally with the current. Therefore, the correct answer is option C: The magnetic field is increased.
